Terrestrial signal combiner 3 inputs: VHF-UHF-UHF
The Televes 433401 is a 3-input combiner for terrestrial signals, supporting VHF and UHF bands. It includes a durable orange mast-mount case for outdoor installations. The combiner facilitates current pass-through from the output to one of the UHF inputs, enabling power delivery to a mast amplifier or a BOSS system.

EasyF Connection System: Simplicity and Savings
The EasyF system offers an innovative connection concept where the coaxial cable's inner conductor is directly inserted into the device, enhancing connection reliability. Eliminating F connectors allows for a reduced chassis size and secures two cables with a single screw.
Key Benefits of EasyF:
- Time Savings: Streamlines installation by removing the need for coaxial cable termination and connector screwing.
- Connection Reliability: A secure clamp prevents coaxial cables from detaching.
- Cost Savings: Eliminates the requirement for additional F or IEC connectors.
- Space Optimization: Inputs and outputs are aligned on one side, preventing cable bending and simplifying work in confined spaces.
EasyF Three-Step Mounting:
Mounting involves simple screw and unscrew operations:
- Unscrew the device cover to access the connection point.
- Insert the stripped coaxial cables.
- Close the cover and secure with the screw.
EasyF System Reliability:
Connections are made via an automated system for inner conductor contact, without soldering. This ensures increased device lifespan, reduced failure rates (avoiding cold solder joints), optimized electromagnetic behavior for high frequencies, and environmental benefits through the elimination of welding pollution and reduced power consumption.
Application Example
The combiner is used in terrestrial signal distribution systems. A typical setup involves connecting VHF and UHF antennas to the combiner's inputs. The output signal is then distributed. The system can also power mast-mounted amplifiers or BOSS systems via a DC pass feature from the output to a UHF input.
Diagram Description: The application diagram shows a Power Supply Unit (PSU) providing 24V to the combiner, which receives signals from VHF, UHF 1, and UHF 2 antennas. The combined output is then routed for distribution.
