PRO-COM150-SRC-2
2-Channel VHF Simplex Relay Combiner
Description
- The PRO-COM150-SRC-2 is an integrated single-tray solution to combine two simplex radios to one antenna.
- When transmitting on one channel, the other channel is switched to a load to make sure that the system is secured against a simultaneous transmission on two channels.
- Minimal rack space required – only 1HU.
- Please specify Tx / Rx frequencies when ordering.
- The PRO-COM150-SRC-2 is a 2-channel VHF simplex combiner with active relays for controlling the switching between Tx and Rx.
- The simplex combiner gives the possibility to combine two simplex radios to one antenna. In the Rx path a bandpass filter, an isolator and LNA is included.
- The simplex combiner safeguards that both radio transmitters do not have access to the antenna at the same time, but the two radios are still able to listen on the Rx channel simultaneously.
- The first radio that enables the transmitter will be able to transmit while the output of the other transmitter will switch to an internal load. When the first radio that enabled the transmitter stops transmitting, the other transmitter is switched to the antenna and allowed to transmit.
- If no radio is transmitting, the system is in listening mode and both radios are able to receive the signal from the antenna.
