RF-382A

® assuredcommunications™ RF-382A Series FAST TUNE AUTOMATIC 400 WATT ANTENNA COUPLER 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 fixedstation 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 Nconnector 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. Specifications for the RF-382A High Voltage Antenna Port Rated RF Input Tuning Capability Up to 150 Watts PEP and Average: 1.6 to 30 MHz: 9 to 35 foot whips; 35 to 150 foot long wires; 40 to 100 foot dipoles (including RF-1912 and RF-1936) Up to 400 Watts PEP; 250 Watts Average: 1.6 to 30 MHz: 75 to 150 foot long wires; 1.6 to 30 MHz: 40 to 100 foot dipoles (including RF-1912 and AS-2259/GR); 2.5 to 30 MHz: 35 foot whips; 4 to 30 MHz: 24 foot whips; 6 to 30 MHz: 16 foot whips Automatically tunes to 50 ohms to within a VSWR of 2:1 200 ms tuning from memory based on prior tuneup.
