ACS-005K

Antenna Control System, VHF/UHF, TX/RX coupler/switch, 30 – 430 MHz

The antenna coupler is intended for use with 9 transceivers plus 4 additional receivers together with three (4 or 5) antennas.  The system has separate paths for VHF (L-VHF + VHF) and UHF.  It is possible to transmit or receive on all channels at the same time.  The transmits insertion loss depends on the number of active transmitters. Low noise amplifiers are used in the receive paths.

When used with five antennas simultaneous transmission and reception is possible. With only three antennas all reception in that band (VHF or UHF), will be disabled when one or more transmitters are active. It is possible to give priority to one transmitter on each band. L-VHF operation is independent of the other bands.  For fail-safe operation, one transmitter on each band is connected directly to the antenna in case of power failure.  An external switch can be engaged to prevent a specific VHF transmitter from the accidental transmission.
