TV signal combiner ZAMEL RSS-SAT1, frequency 0.3–2400 MHz, 1x2 RTV-SAT splitter with SAT summing

ZAMEL RSS-SAT1 is a compact TV signal combiner and 1x2 splitter designed for integration of terrestrial RTV and satellite SAT signals across a wide frequency range of 0.3–2400 MHz. The unit combines terrestrial antenna and satellite feeds using an internal summing stage and provides two equivalent outputs for distribution to multiple receivers or rooms. Its form factor and functionality suit small home and light commercial installations where a simple, passive solution is needed to merge and split RTV and SAT signals.

Advantages

The device supports a broad frequency band from VHF and UHF terrestrial channels up to satellite frequencies, enabling simultaneous handling of multiple signal types without active power. It integrates summing and splitting in a single passive unit, reducing cabling complexity and the need for separate components. The splitter provides two outputs with consistent passive distribution, and the compact design allows easy mounting within typical wall boxes or equipment cabinets.

Suitable for

• Home installations combining terrestrial antenna and satellite SAT feeds
• Small apartments or multi-room setups requiring one input split to two receivers
• Light commercial or office environments with low-complexity TV distribution needs
• Situations where a passive, power-free combiner/splitter is preferred

When it may not be suitable

The RSS-SAT1 is a passive device and does not provide signal amplification; in cases of weak incoming signals or long cable runs it may not maintain adequate signal strength and an active amplifier or distribution amplifier may be required. For larger multi-point distribution systems or professional headend setups, devices with more outputs, gain control, or powered processing would be more appropriate.

Key specifications

• Frequency range: 0.3–2400 MHz
• Functionality: RTV (terrestrial) and SAT (satellite) combining with 1x2 splitting
• Passive operation: no external power required
• Number of outputs: 2 equivalent outputs
• Application type: indoor mounting for home or small installations

How to use

Connect the terrestrial antenna feed to the designated RTV input and the satellite dish LNB to the SAT input according to the device markings. Route the combined outputs to receivers or wall outlets using quality coaxial cable and appropriate F-type connectors. Ensure connections are tightened to prevent signal loss and place the unit in a dry, ventilated location away from strong electromagnetic interference. If signal levels are insufficient after installation, consider adding a powered amplifier upstream of the combiner or using shorter, higher-quality cabling.

What to consider before purchase

• Check incoming signal strength and cable lengths to determine if a passive splitter is sufficient
• Confirm compatibility of satellite LNB type and terrestrial antenna with your receivers
• Plan the number of required outputs; this model provides two outputs only
• Consider indoor mounting location and space for connector access

Usage recommendations

For optimal results, use low-loss coaxial cables and maintain short cable runs where possible. Test signal levels at each receiver after installation and, if needed, add a powered distribution amplifier before the combiner to compensate for losses on long runs or weak sources.
