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.
This will help determine the correct RF budget calculation.

H-SP-1x12 is a 1x12 CATV RF Portable ( not 19" rack sock-monable ) Splitter distributes a single coaxial RF signal to 12 outputs for cable TV, HDTV, QAM, ATSC, and commercial television distribution systems. Designed for 5-1000 MHz operation, this passive 12-way splitter features F-type coaxial connections, a shielded metal housing, and a compact vertical connector design for reliable indoor and outdoor RF installations.
The Thor Broadcast 1x12 CATV RF Coaxial Splitter is a professional 12-way passive RF distribution solution designed to divide a single RF input into 12 separate coaxial outputs.
Supporting frequencies from 5 MHz to 1000 MHz, this splitter is ideal for distributing CATV, digital HDTV, QAM, and ATSC television signals across multiple televisions, receivers, and RF distribution networks.
The splitter features a circuit-board design and solder-backed metal enclosure to minimize electromagnetic (EMI) and radio-frequency interference (RFI), helping maintain signal integrity.
Its vertical F-type connector arrangement allows convenient coaxial cable installation. The weather-resistant construction makes it suitable for both indoor and appropriately protected outdoor applications.
Ideal for hotels, motels, apartment buildings, schools, hospitals, fitness centers, commercial facilities, and MATV/CATV systems.
1 Input / 12 Outputs: Distributes one RF coaxial feed to 12 destinations.
5-1000 MHz Frequency Range: Supports standard CATV and television distribution frequencies.
Digital HDTV Compatible: Suitable for distributing ATSC and QAM RF television channels within the supported frequency range.
Passive RF Design: No external power supply required.
F-Type Coaxial Connections: Convenient connection to standard coaxial distribution systems.
EMI/RFI Shielding: Solder-backed metal housing helps reduce external interference.
Two-Way RF Compatibility: Supports compatible bidirectional CATV distribution applications.
Vertical Connector Layout: Convenient cable management and installation.
Indoor/Outdoor Applications: Designed for installations requiring weather-resistant RF distribution hardware.

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 to 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.
