The RF-382A Series couplers efficiently and automatically
match the output of 125 to 400 watt transceivers to a wide
variety of whip, dipole, and long-wire antennas over the
frequency range of 1.6 to 30 MHz. Tuning time from memory
is less than 200 milliseconds.
RF-382A Series couplers operate with ALE communications
systems that require very fast frequency change. Rugged and
reliable, they operate under the most severe environmental
conditions in vehicular, transportable, shipboard, and fixed-
station applications.
The RF-382A Antenna Coupler is designed for direct interface
with FALCON^® II HF systems and is fully compatible with the
built-in MIL-STD-188-141B and STANAG-4538 Automatic Link
Establishment (ALE) protocols.
The coupler requires a control cable and RF coax interface to
connect to the associated transceiver. Separation can be up to
250 feet (76 m). A high voltage ceramic insulator provides the
connection to the antenna. It is also equipped with a 50-ohm N-
connector antenna port for coaxial connection to a fixed site
broadband or resonant antenna.
Internal built-in test to the module level provides rapid
diagnostic troubleshooting and repair. In addition, all key
operating parameters are continually monitored during
operation. If parameters are exceeded, a coupler
fault is reported to the radio.
