Yaesu FC-40 Automatic Antenna Tuner

  The FC-40 is a microprocessor-controlled antenna impedance matching network designed to provide all-amateur-band transmitting capability with the FT-897/857 Series of transceivers, when used with an end-fed random wire or long whip antenna. The FC-40 makes use of the control circuitry built into the transceiver, which allows the operator to control and monitor automatic operation of the FC-40, which mounts near the antenna feedpoint. The FC-40 uses specially-selected, thermallystable components, and is housed in a waterproof case to withstand severe environmental conditions with high reliability.
