Broadcast your video to the unlimited TV's build your own private headed HDMI Modulator

This video shows how to build a broadcast CATV RF headend using Thor Broadcast HDMI modulators. Easy to install digital modulators, similar to when archaic analog modulators were still commonly used. Now you can use any video source like security cameras, computers , DVD players, Roku player, Google Chromecast, Cable TV STB, Satellite STB and other HDMI output devices and send the video out as a modulated channel of your choice. The modulator can generate CATV RF CABLE TV QAM or Off the Air ATSC; or used in foreign countries that use DVB-T or ISDB-T. It's a very convenient system because the front panel show modulated channel and all connections are on the back, like HDMI inputs and RF F-type connector outputs. The RF Outputs can be cascaded or, even better, connected to a 1x12 CATV RF combiner, combined coax will have all 12 or more channels on it; and depending how many TV's the signal is being distributed to, might need to use an inline CATV RF amplifier then distributed using RF splitters and taps. Please note that if the coax distance is very long, Thor manufactures easy to use RF over fiber solutions as well. Please note that if the COAX distance is long Thor offers easy to use RF over fiber solutions as well.

HDMI Digital HD Modulator - CATV over coax distribution - high video quality and low latency

This video demonstration includes our THOR RF PETIT modulator ($384) which is being used to send an HDMI signal, a ROKU stick which is streaming just a countdown timer on YOUTUBE App. You can see from the first TV that the timer is moving in realtime using the HDMI loop-out feature of the HDMI modulator. So the TV's to the right have been sent the CATV QAM signal through an RF CATV 1x8 splitter, then into the back of each tv. As seen, there is a very little delay which makes it excellent for any realtime LIVE event like sports, theatre, house of worship. Using the ROKU stick, the modulated signal is going to the TV's in HD 1080 signal which makes it ideal to stream movies, sports, or anything else you can find online to stream. link to the specifications https://thorbroadcast.com/product/petit-hdmi-rf-modulator-1.html

Question and Answers

Question:

1)We have a channel that we insert into our cable providers system. They supplied the original modulator but it is failing and they have implied that they are not going to give us another one. Will this unit take its place? Our cable system does use DTAs for all the televisions.

2) the cable co uses ch 5 the virtual channel on the cable boxes is 98. Can you tell me how to program that? I have already been successful in getting into the unit but do not know where to program.

Answer:

The answer is Yes, any of our Qam modulators can be used for Channel insertion, you just need to find out what channel the Cable company has dedicated for the insertion.

If you still have an old encoder with web access, we could retrieve this information if you send us a screenshot.

We need to know the physical channel number and VCT virtual channel number.

2)

If your cable company is using channel # 5, please select Frequency - 79Mhz ( this is the corresponding frequency for DVB-C QAM channel #5).

Change the VCT Major number from 5 to 98

Once you press apply, the unit will generate physical channel number # 5 (79Mhz) with virtual channel number Majo 98 and Minor 1

If you plug in the coax output directly to the TV and scan your channel, the TV will display channel 98.1

Question:

Now I messed up the password and I don’t see a reset how do I reset to default?

Answer:

You can reset the device from the front LCD panel. Press the middle button on the Petit that looks like a box with 3 lines in it. The first time you press it, it will show ATSC or J83b. Press it again and it will show DHON or DHOFF. On the third time, you press the button it will say ASR. When you get to the ASR button press the down arrow to execute the factory reset. The process should only take 30-60 seconds and you'll be back up and running. If you have any further questions please don't hesitate to contact me.

Question:

Hi Thor support team, I have a customer who needs to add a TV channel to their existing TV network to provide information to the end-users. Their source has an HDMI output. They have about 90 displays spread out in different floors. Following drawing is the best representation based on the information I got from the client. Document also attached. I need guidance on which one of your products to use. Is H-HDMI-RF-PETIT good product for this situation?

2) This is the first time I am facing this type of problem, and I appreciate your help. As you see from my drawings, there are about 90 displays existing, spread over several floors, of a county jail. All coaxial connections to TVs are daisy chained from two outputs of the Blonder Tongue amplifier; see my drawings. I assume each output of the Blonder Tongue amplifier feeds 45 TVs, but I could be wrong. They need to add a channel to the existing rage of channels that broadcast safety and hygiene messages. The TVs are small and mostly old; from old CRT to new 19" flat panel TVs. Of course, the content will have video and audio, but there is no special resolution or audio requirement. A standard resolution and audio quality would be fine. Latency is not an issue since all displays are very far apart. Now that I think about it, a single HDMI input may not be enough, if they want to add more contents later on. Do you have a device that has multiple HDMI inputs? Also, where should this device be placed? After the Vecima box? After the splitter and before the amplifier?

3) Although the Comcast equipment is 2 city blocks away, we can put the equipment near the amplifier which is in the jail building. Client wants to broadcast their message on channel 2. If I use Thunder-4, what type of coax combiner should I use? Also, you probably have taken into account the required modulation type in your answer. I am just curious, what type of modulation should be used in this application?

Answer:

Do you have any more information of what the application necessitates besides HDMI? Do you they require certain resolution or audio capability? Is the latency or size of a unit an issue? We have a plethora of units that can fit the information you provided. The Petit would seem fine, or the AC3-CMOD, we also have multi-channel units like the Thunder-4... All can take HDMI and output to RF

This is the link:

https://thorbroadcast.com/product/1-4-or-8-hdmi-digital-rf-encoder-modulator-8230.html/238

2) The modulator should be able to feed all of the TV's. I would think you'd want to put it near the other Comcast gear. But it does it's 2 blocks away? Is there another headend room or electronics closet closer to the facility you can put the equipment in? In either case you can use the RF Petit, or you can use something like the Thunder-4 for multiple HDMI inputs. All you need is a coax combiner, to get the feed from Comcast and our units together. You also should find out which channels are being unused by Comcast so you can put the QAM channels on open frequencies.

3) Yes you can put it on channel 2; any RF combiner from 5-970mhz will work. I assume you will need QAM 256

Question:

I found a YouTube video of yours and thought I would send you a message. I'm in a 35 unit condo building and we have an old but still working, security camera in our front entrance. It has a composite video (single yellow RCA) output that we convert to RF VHF channel 6. We have installed an HDTV antenna on the roof and about half of the owners use it. Do you have a low-end product that would allow us to broadcast the video over an HD channel so owners could tune to a channel to view the camera?

Answer:

We have a perfect device for ATSC private channel injection for that camera.

If you keep the Analog RCA Camera then we'd have to get you an RCA to HDMI converter, then you can use something small and compact like the PETIT modulator, this unit only takes in HDMI.

So you can upgrade your camera to and HD HDMI output camera, and just, plug indirectly, otherwise, we need to get you a converter with the above product.

Question:

1) I am on the phone with the cable company and he says I need to change the coax modulation ATSC setting to DVB-t to work but I cannot see where to change it also needed to be mpeg2 and I found that setting

2) I sent that back to the cable company and he called me back and said he neglected to tell me DVB-C Annex B is what he needs. How do I set that? I do not see that as a choice.

Answer:

1) If you log into the NMS GUI through any web browser, there is a menu in the modulation settings to change that.

Once you get to the menu the password is THOR in all capitals, it will allow you to switch to DVBT

one thing I want to point out DVB-T is a European standard, are you trying to get it working in the USA Canada or Mexico? If so it should be DVB-C Annex B or ATSC so it works with North American television sets.

American TV sets won't have DVBT tuners built-in.

2)

Yes, this is correct, the DVB-C Annex B is actually Annex J.83b, please change it to J.83B, from the modulation menu or reset unit the default configuration, The default is J.83B channel 2 (57mhz)

Question:

Just to let you know that the two Pedit modulators you shipped me last week have been installed and are doing well. I was very satisfied with their quality and performance

2) I did observe one small issue that would benefit from your attention. The single sheet enclosure in the box said to look in the manual for the instructions to change the subnet on my computer. Being and elder technologist (od foggy), it took be quite a while to fathom that I was supposed to use my phone to photograph the pattern and download the manual. The manual included in the box certainly didn't cover that. In any case, adding a couple of lines of explanation and perhaps a written out URL for the phoneless would fix the problem.

Answer:

Hello, that's great news. Happy to hear the install went well.

2) Yes, we totally get that. They just so happen to be countless helpful documents on the product page, which can be downloaded, and also a bunch of instructional videos on how to do that. The box is pretty small and we just put in the install manual; all other docs and helpful tips tricks and extended installation docs we leave up on the website. Perhaps we should add a note in the units box that those are available via the web

Question:

I had is to turn the power upon the modulator for a long COAX cable run. is it better to turn the gain up or down and what is the maximum?

What would be the best RG cable to use?

Answer:

The RF Petit modulator has about +35dbmv RF output power, but next generation will have +40dbmv RF output power, same as the 4ch HDMI modulator

RF is a bit like water pressure, it is being lost traveling over the Coax, depending on channel frequency and coax cable type

this is the insertion loss by frequency a cable:

Question:

I was looking at the Model H-HDMI-RF-PETIT.

What I need is a residential distribution system for about 4-5 TVs. I need 1 maybe 2 HDMI inputs along with a digital off-air input as well. The signal will be sent using RG6 throughout the house. Is this the best model for my application? What kind of loss should I expect from the 1080 sources? I was using a Channel Plus 3025 that finally quit and is discontinued. I want to modernize and upgrade for the best money.

Thanks in advance for your help. Your prompt reply will be appreciated.

Answer:

If you need to use an Antenna, and need a couple HDMI sources converted to ATSC channels to watch along with your Antenna, these would be a great fit.

Simple to use, compact, Full 1080 Picture quality is excellent. Use a combiner to get all the sources in the same RG6 to inject into the rest of your system.

Units are readily available and have tech support included, along with a 30 day moneyback guarantee.

Let me know if you have any specific questions about operation or setup, but it looks like you're just replacing an older analog unit, so this should be a smooth transition.

Question:

I would like to find a device that:

- connects to the cable system at a 50 bed assisted living facility to show content on a certain tv channel

- would like to connect a laptop to the 'device' and broadcast whatever is showing on the laptop to a tv channel on all tvs

- would like to have a dvd/vhs player connect to the 'device' and broadcast to all tvs

broadcast video and sound to all tvs

Answer:

How many HDMI sources do you have total?

i figured i could buy a splitter if needed. Also a computer with dvd player and cut out the vhs

So just one HDMI source?

yes

This is a very popular choice for lower budget scenario's https://thorbroadcast.com/product/petit-hdmi-rf-modulator-1.html

this is what currently use = DVISn Nano Encoder – RF Out

The DVISn (Nano) encoder/multiplexer with RF output is the most cost-effective and smallest form factor solution within the DVIS line of products for inserting locally generated content into an MDU, hotel or commercial property in digital format. It is ideal for applications requiring a low-cost, basic solution for SD MPEG-2 encoding and QAM-based distribution or insertion of locally generated content into a coax network. Extremely compact and wall mountable, the DVISn device fits into virtually any space and includes fully integrated audio/video encoding, multiplexing and QAM modulation.

We can add this HDMI "Channel" to an assigned number not being used by your current CATV system, and any TV set to that channel wil be able to get the TV

so it should be easy to swap devices ?

Yes very much so

we can even preconfigure the device to your current settings so when you get it, you just have to plug it in

do use third party to come on site ?

or I should be able to handle ?

You should be able to hook up a few cables

we will set it up like your current unit, all we need to know is which channel you're currently sending video on

dont recall - but i find out when time comes

so its matter of ordering via thor website and you config and ship and i plug in - done?

correct

just send us an email after you order with the information we need, and we'll do the rest

Question:

I'm a tech support volunteer at a continuing care retirement community. We operate three in-house TV channels and currently use two of your CATV modulators. We are operating at the top end of the CATV spectrum on channel 122, at 860 MHz. I'm interested in replacing a 700-foot cable drop (RG-6) with fiber. The cable is already in place, with several free strand pairs, so all that's needed would be a transmitter/receiver pair. What do you offer?

Answer:

https://thorbroadcast.com/product/thor-optical-mini-catv-rf-transmitter-45-1000mhz.html

this is the least expensive transmitter we offer

https://thorbroadcast.com/product/thor-fiber-optical-mini-ftth-rf-catv-cable-tv-receiver-8230.html

https://thorbroadcast.com/product/rf-catv-mini-optical-receiver.html

We have two compact optical RX options

RF over Fiber equipment only works on singlemode fiber. hopefully thats what you have installed. If you have multimode, nothing in the world will work.

That's bad news, because I'm afraid the cable is multi-mode.

You can not put RF on multimode fiber. flat out doesn't work.

How can I tell what type of cable has been installed?

single mode cable is usually yellow

MM is usually orange

Ours is orange. OK, and thanks for the input. Time to think about a Plan B, which would involve replacing the RG-6 with a better grade coaxial cable. What would you recommend?

RG 6 is the standard most people go with.

You can go up to RG11

but realistically at 700ft you'll need Amps regardless

https://thorbroadcast.com/product/distribution-amplifier-30db-54-1000mhz-coax-catv-qam-atsc-analog-rf.html

We're getting way too much signal attenuation over a run of that length.

Might be an easy solution if you just have the one run giving you issues. Then again if you think your cable is damaged, installed poorly, thus giving you too much attenuation then replace it with RG 11 and throw on a DA

technically speaking you shouldn't even be able to get a signal on the other side

900MHz

20.1dB

6.0dB

5.4dB

So in this table RG 6 versus RG 11 is only .6db of loss difference per 100ft

I would get an amp, don't worry about the cable

It's just that single long run. The rest of the CATV distribution system uses amps.

if its RG59 then replace the coax, if its RG6 then leave it

our amp is +30 db so you'll replace about 500ft of cable with one unit

Tx

Does the amp go at the transmitting end or the receiving? Or in the middle?

depends on how much power you're reading at the transmission site, if its high, then go middle, if its low at the outset, then go transmission then middle

get an RF meter and check the power at multiple points and see where you are

you don't want to overdrive the signal to high and then go too low, you'll degrade the quality that way

Are you recommending a specific amplifier?

ours never have issues

https://thorbroadcast.com/product/distribution-amplifier-30db-54-1000mhz-coax-catv-qam-atsc-analog-rf.html

The RG-6 is in the ceiling. To stall an amp at a half-way point would require an electrical outlet that's not there.

Question:

Is it any other way I can distribute HDMI over our facility?

Answer:

There are some other was to deal with the HDMI real-time distribution

1) HDMI over Ethernet, this is also a very convenient day and not
noticeable delay
https://thorbroadcast.com/product/4k-hdmi-over-ip-ethenet-cat6-rj45-extender-300feet-with-8230.html
2) HDMI over fiber

Question:

I’m the technical officer on a pipe lay vessel and I am looking into a replacement TV distribution system.Our current set up is we have our satellite controller installed and receive the signal through it and then this is connected to local decoders which are purchased in the region we are working. From the decoders we go to modulators and distribute on analogue around the vessel.We are starting to see out modulators fail and as a result we are looking at new options. We are also now having to use HDMI to AV scalers as most decoders are only HDMI so not Aux (red/white/Yellow) and our current modulators only have a aux to 3.5mm av jack input. With this set up we are loosing quality and introducing noise in our system. I have seen your rack mounted system Petit-12CH-RM and I am looking for some advice as tv distribution is not my strong field. We would b looking at pushing up to 20 channels out around the vessel so I understand we would require two of these units, can they be put in series for that many so in effect 24 channels. I presume these are standard digital outputs and we can tune any tv worldwide into them. Does each modulator require its own power supply or is there a unit that can be used to do the whole rack frame. We do have some analogue inputs we need to transmit but I can use scalar to do that as I don’t think your rack system could take them, Im looking for the best option for the system. That is easy to maintain and set up.Any help or guidance on this would be appreciated

Answer:

Yes this system sounds like it would be ideal for you.

We do have 1RU power strips you can attach to the rack which have 8 outlets in each.

This is a popular option; the other option is using a multi channel modulator, currently the Thunder-4 is at a great price so it works out to be about the same.

https://thorbroadcast.com/product/1-4-or-8-hdmi-digital-rf-encoder-modulator-8230.html/238

In this case you would need 5pcs of the Thunder-4 to output 20 channels, using an RF combiner, and less power supplies.

All of our units are digital modulators, they don't output analog.

Let me know if you have any other questions, or thoughts, what your preference is etc.

Question:

Good day sales team I am looking to replace several Pico Digital SDQ6. A 6 channel SD encoder QAM/Modulator. I have a private housing complex where I modulate a 60 channel private TV system. By any chance do you have equipment that can replace this one?

Answer:

We have a lot of options for Qam Modulators. We have 8 Channel HDMI input modulators https://thorbroadcast.com/product/1-4-or-8-hdmi-digital-rf-encoder-modulator-8230.html/239 They are a great value for price per channel. Terrific HD picture. We also have individual units like the RF PETIT that can be mounted in Chassis as well https://thorbroadcast.com/product/petit-hdmi-rf-modulator-chassis-system-for-1-12-units.html/254 How many channels are you looking to do out of the 60? Or do you need all 60 replaced?

Question:

Is there a way to boost power or do I need an amplifier? Thanks

Answer:

The maximum RF output power from the modulator is +32dbmv

Please log in to the modulator, the IP address is 192.168.1.10,

Please check attached instructions as well

In the Modulation Parameters you can set attenuation so the strongest signal is with the "0" attention value.

If you need more than +32dbmv than you would need to use amplifier, or we do have other modulators with the strongest RF output power

Question:

I have a couple questions about your RF modulator

I am looking to use an RF modulator to distribute video to 5 TV's we have outside in our service drive at our car dealership. I will need to split 1 to 5 and those 5 displays are about 150 feet away from the source. What splitter should I use?

Also, do y'all have dealers around Dallas, TX where I could go purchase your products?

Answer:

Any splitter should work fine

We do have integrators in Texas, but resellers are online mostly

Ok, thank you. Thats what I needed!

No probelm

problem

Do you think just a regular splitter or an amplified splitter?

depends on the coax run

and the particular modulator you're looking at

Petit HDMI RF Modulator. Then about 150 ft run to the splitter and then short runs to the display. At most 30 ft.

I think you should be fine

Ok cool. Thank you.

standard splitter for 45-900mhz will be okay

satelite dish splitters go 1ghz to 2.4ghz

a regular old splitter is very inexpensive

Question:

I have a Thor digital TV tuner (H-STB-QAM-ATSC) and a Thor Modulator (H-HDMI-RF-PETIT). How do I tell the modulator to switch from coax (antenna input) to HDMI (DVD player) input?

Answer:

First, please forgive my lack of "tech" terminology regarding your manuals.

I have a Thor digital TV tuner (H-STB-QAM-ATSC) and a Thor Modulator (H-HDMI-RF-PETIT). How do I tell the modulator to switch from coax (antenna input) to HDMI (DVD player) input?

Hello

The modulator outputs a signal via RF from the HDMI source

so it needs to be on a vacant channel, if your antenna feed has channels 2-40 then put our modulator on channel 41

I will give that a try. Any vacant channel? I believe my antenna receives channels up to 58. Also, what channel should the Tuner be on or doesn't it matter?

the tuner can be set to the channel you want to watch

okay then set the modulator to 60

after that you need to rescan the STB for AIR

so it picks up your antenna, and also make sure the modulator is set to ATSC, not qam

Thanks. I will try that. Hopefully all will work fine. If not, I'll beg for more help!

you can also call tech support if you get stuck again, 1800-521-8467 ext 2 and they will help you resolve the issue

I can't call, because our cell phone doesn't get a signal at this location. I set the modulator to channel 65 and did a tuner rescan, with no results. Channel 65 does not show up on the tuner.

is the modulator set for ATSC?

and you're doing a scan for AIR on the STB

I need help with the terminology, please. How do I determine these 2 settings?

Using those 3 buttons you can setup the following:

1) Change the channel number

2) Press HOME 1 time: changes the CABLE QAM (J83b) to AIR ATSC modulation (vice versa)

3) Press HOME 2 times: changes DHCP ON or OFF

4) Press HOME 3 times: Reset to default configuration (factory reset)

https://thorbroadcast.com/ is sharing a file with you. h-hdmi-rf-petit-quick-connection-instructions1.pdf - (Size:2.82 MB)

This is the manual for the modulator

so if you click the menu button on the front of the unit and it reads J83B then that is QAM, you need to change that to ATSC which is terrestrial antenna signal

QAM is Cable and ATSC is Antenna essentially, those are the two standards we use in North America

So we just need to get everything on the same standard, if you have an antenna on your house, then we need the modulator and STB decoder box to also be setup for Antenna, which is ATSC

The modulator offers 3 digital readout: J836, dHOF and ASr. Am I to use the ASr setting when scanning?

no stick on J83B which is north american QAM, press the down when its highlighted and it should switch to ATSC

press up on J83B to switch, then DOWN to SAVE

ASR will reset the unit back to factory settings, so don't play with that

Got it!! Thanks so much. So now if I replace the DVD player HDMI with a ROKU HDMI all should work well, yes? Again, thanks.

Question:

Looking for a method to merge an amplified OTA HD TV antenna with the single HDMI output of a DISH Hopper 3 over a single RG-6 coax cable to two remote HD TVs. Also, need a loop-out of the HDMI source (Hopper 3) for a HD TV located at the source (don't want to lose HDMI quality input for the TV near the Hopper source). Hopper 3: output resolution 1080p or 4K 60FPS (10 bit color); output format HDMI 2.0 and HDCP 2.2. ====== It appears that the H-HDMI-RF-PETIT (THOR HDMI HD Digital RF Modulator sold on Walmart) might fit except for the loop-out and HDCP2.2 spec. Is the H-HDMI-RF-PETIT compatible with HDCP 2.2? Note: Also, looking at placing a 1x2 HDMI splitter

Answer:

Yes that HDCP will work, you can find more specs on the product here

However this is not a 4k resolution product, so your dish hopper would
be better suited if you set it up for 1080i or 1080p/60
We do have 4k Resolution HDMI modulator, H-4K-UHD-QAM-IP

Question:

We have a Petit HDMI RF modulator connected to an ATEM Mini Pro
Extreme. The modulator is sending our signal out via RG6 coax to a
splitter where we have multiple TV's connected. We are a church, and
so these monitors are located in various spaces outside the sanctuary
for viewing. However, when turned on, the TV's all have a signal lag
behind the live version of somewhere in the 1.5 . Is
cthe RF modulator causing this and what can be done?

Answer:

The encoders in an MPEG-2 system have a delay by nature. The encoder
takes in an uncompressed video or audio signal and applies various
techniques to reduce the data rate, so it can be sent as a modulated
TV channel.
The decoder, or TV tuner, also has some delay as it processes the
encoded data and reconstructs the original signal.
This process takes time and there is nothing that can be done to
eliminate the delay completely.
However, the delay should not be greater than 0.8-1s.

If there is a delay greater than 1s, it is likely that the delay is
coming from something other than the encoding and modulation process.

To test the delay caused by the modulator alone, you can send a clock
signal from a PC to the modulator and to a TV.
Take a picture of the PC screen and the TV next to it, and you will
see that the modulator delay should not be more than 1s.
It's possible that the delay is coming from the ATEM Mini Pro Extreme
or a combination of the ATEM Mini Pro Extreme and the modulator.
this is link to the Timer video you cosul use for testing:

There are different professional and commercial modulators available
that have different chipsets. They can encode and modulate at about
0.3-0.5s, for example,
the H-2ADHD-QAM-IPLL
(https://thorbroadcast.com/product/2-hdmi-ypbpr-hd-digital-tv-modulator-qam-atsc-dvb-t-8230.html).

Question:

I have a Thor H-HDMI-RF-PETIT which broadcasts on channel 4.1. Is it possible to add a second one and have it broadcast on channel 4.2?

Answer:

The Petit modulator is capable of generating a single physical cable channel based on the frequency chart/channel table.

https://thorbroadcast.com/upload/files/220/catv-qam-channel-center-frequency.pdf

It doesn't have a transport stream multiplexer built into it, it cannot multiplex two programs on a single channel.

You can, however, place these programs on two separate physical channels. For example:

CH4 - 69MHz

CH5 - 79MHz

You can then assign VCT virtual channel numbers, such as 4.1 for the first program and 4.2 for the second program.

This way, the TV will scan and display visual channels, regardless of the fact that they are being transmitted on physical channels 4 and 5.

Please let me know if this explanation is clear.

If you require the ability to multiplex two or more programs on a single frequency, we do have other multi-channel modulators available.:

H-2ADHD-QAM-IP-LL

Question:

I found out we need 12 inputs, not 8-10. Any pros/cons of going with the Petit w/ 12 modules (and PSU) vs a Thunder 8 and a Thunder 4 to get us a total of 12 inputs? Less wiring? Less network lines/rack space? What would you recommend? A quote would be great. I don't think we need the RF Combiner, if I'm pulling the blonder units and putting these in I think we already have the RF stuff.

Answer:

At that point yes, those are the more obvious differences. There really isn't much of a difference past that; the petits will take up a lot more rack space, plus you'll need accessories like the PSU and Combiner.

Using an 8 and a 4 obviously means more rack room, less wires and initial implementation and setting or troubleshooting time is much quicker, so installation officiency is much better.

The difference in actual modulation and power to encode isn't much different on these devices specifically, compared to other ones we have on the shelf.

Both of those were designed to be easy to use and provide excellent picture quality. You can't go wrong either way; it's up to a designer's choice at this point. I personally would go less rack space and less clutter by design choice, but every one usually has their opinion on that matter.

Question:

Wiil the blonder tongue MIRC-4D HE-4 Series Rack Chassis and Power Supply work for your modulators ? Will it fit ?

Answer:

No unfortunetly not we do have our own mouting system for multiple HDMI modulators and our own power supply ,

part number: H-PS-12X16 , H-RM-PETTIT, H-LB-PETTIT

Question:

I have a Petit HDMI RF Modulator (H-HDMI-RF-PETIT)

I'm trying to connect a Roku to the HDMI port and the RF just goes out
to an old analog B&W television set.

I can't seem to get any signal - I just get static. I'm using channel 2
and it's set to ATSC.

What are the best settings for a 70's B&W TV?

to Matthew, Support

Hello Matt,

Thank you for contacting us.

The most likely problem you are having is that your old TV does not support Digital ATSC of Air or Digital QAM RF.

You can easily find out by connecting an off-air antenna and scanning for Air channels. If the TV finds digital channels like 2.1, 3.1, 4.1, etc., it means that your TV supports digital signals.

In that case, we will advise you on what to do.

If not, it means that your TV only supports Analog Modulated RF - NTSC.

Our Petit Modulator supports Digital modulated signals, not analog. However, there is a workaround.

You can connect our Petit modulator to the Digital tuner H-STB-QAM-ATSC.

That tuner will scan and find the digital channel the Petit is generating and output an ANALOG RF - NTSC output on channel 3 or 4, you can then connect to your TV

H-STB-QAM-ATSC

https://thorbroadcast.com/product/qam-catv-rf-and-atsc-rf-to-hdmi-decoder-stb-8230.html

Please let me know if this is clear. Otherwise, you can run this coaxial cable for the Petit to all your Digital TVs, and you can enjoy full HD video and audio.
