Antenna Control System, HF/VHF, TX/RX coupler/switch, 1.6 – 88 MHz
The antenna switch is intended for use with 5 transceivers together with 1 or 2 antennas. During transmission, the active transmitter is automatically connected to the antenna, while an inhibit signal is issued to the other transmitters – the receivers are either disabled or connected to the (optional) receive antenna.
The received signal is amplified and distributed to all receivers with a low noise amplifier.
It is possible to give priority to one transmitter. For fail-safe operation, one transmitter is connected directly to the antenna in case of power failure. The unit uses vacuum relays for fast/high power switching. RF sensors are used for TX/RX switching.
Ethernet and USB connectors are available for remote control, and interfacing to the radio system. A ¼ VGA display is also used for control and indication
