Antenna Control System, VHF/UHF TX/RX coupler/switch, 30-512 MHz


The antenna coupler is intended for use with 4 transceivers plus two additional receivers together with one (or two) common antennas. It is possible to transmit or receive on all channels at the same time. The transmit insertion loss depends on the number of active transmitters. A low noise amplifier is used in the receive path.

When used with two antennas simultaneous transmission and reception is possible. With only one antenna all reception will be disabled when one or more transmitters are active.

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.

See datasheet for a closer functional description.
