ANTENNA COUPLER - 2 Pages
30.05 2007
COMROD ACS-005K
VHF/UHF TX/RX coupling unit
Application:
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 transmit 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 from
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
accidental transmission.
