These are simple plug-and-play devices that can be installed in minutes.
Each one of them has different insertion loss; please check the individual units for more information.
The table below shows the insertion loss in dB per 100 feet for COAX (RJ-59, RG-6, RG-11) depending on the frequency.
It will help to determine the correct RF budget calculation.

The CATV RF coaxial network can be designed in many different ways, depending on various individual factors, such as:
Each splitter has its own insertion loss, which is why the RF Power Meter H-RF-MET is a handy tool for installation and troubleshooting. Here are links to the RF Power Meter and CATV RF Amplifier, in case they are needed for your installation or troubleshooting." Let me know if you want to adjust anything further! |

You can use different techniques to distribute a signal to 20 TVs depending on their locations. The Petit Modulator outputs 30 dBmV RF power. The lowest level a TV can detect is 0 dBmV. Different splitters have different losses, called insertion loss. For example, the H-SP-1x2 has a 4.5 dB loss, the 1x4 has a 7.5 dB loss, the 1x8 has an 11 dB loss, the 1x12 has a 16 dB loss, the 1x16 has a 16 dB loss, and the 1x24 has a 21 dB loss.
Knowing this, you can use just 1x24 splitters and run individual coax cables, or you can use a combination of splitters and calculate the total loss to ensure it is less than 30 dB. For example, you can use a 1x2 splitter first, then run two coax cables to two 1x16 splitters, or use a 1x4 splitter with four 1x8 splitters. This way, you create zones and save on coaxial cables.
You can also use a combination of splitters and taps. A tap has an input, a drop, and an output. It has a small insertion loss between the input and output, and the drop is dedicated for TV connections. Taps allow cascading, which means you can use a 1x2 tap for each TV and cascade the output to another tap. This method allows cascading and saves on the amount of coaxial cables you will use.
The most important thing is to ensure you do not lose more than 30 dB. If you need more than 30 dB, you would need to use amplifiers in your system.

Rackmount 19" Power Supply 16 port 12V 1.5A DC
Universal 16 port 12V 1.5 DC Power Supply, standardized use for an application that many 12V devices need to be powered. Used for Cable TV STB's, HDMI and SDI Modulators. Eliminates the need for individual power supplies, 19" rack mount form factor makes it easy for clean headend installations.
Fiber Optic Power Meter Universal connector ST, SC, FC
The handheld optical power meter is a fiber optic test instrument. Fiber-optic installations require end-to-end optical loss measurements. The meter can measure eight standard WDM and CWDM wavelengths: 850nm, 980nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm, and 1650nm. It has universal ST, FC, and SC interface connectors, making it a very convenient and universal tool.
