FC-40 External Automatic Antenna Tuner
The FC-40 is a micro-processor controlled antenna impedance matching network designed to provide all-amateur band transmitting capability with many of Yaesu\’s Transceivers, such as the FT-950, FT-450, FT-897 and the FT-857. This tuner is to be used with an end-fed random wire or long whip antenna.
The FC-40 is a microprocessor-controlled antenna impedance matching network designed for use with the FT-950, and all versions (original and “D”) of the FT-450, FT-857, and FT-897 HF/VHF/UHF Transceivers. The FC-40 makes use of control circuitry inside the transceiver, allowing the operator to monitor and control operation of the FC-40, which mounts near the antenna feedpoint. Fully waterproof, the FC-40 may be mounted outdoors in exposed locations, and will handle a 100 Watts of transmitter power.
The FC-40 is designed for operation on 7 ~ 54 MHz, when using an 8’ whip like the YAESU YA-007, or on 1.8 ~ 54 MHz when used with a random-length wire longer than 66’. Matching time is typically five seconds or less, and the required drive power is 4 ~ 60 Watts. The FC-40 sports a whopping 200 match-setting-point memories, for instant recall of the tuning settings
