FC-10 & FC-800 REMOTE AUTOMATIC ANTENNA TUNER OPTIONS

Both the FC-10 and FC-800 provide all-band transmitting capability with an end-fed random wire or long whip antenna (the FC-1 0 antenna tuner should be used with antennas requiring coaxial feed line, such as beams). Both tuners make use of the control circuitry built into the Yaesu FT-840 (FT840, FT 840) , which allows the operator to control and monitor automatic operation of the FC-10 or FC-800 mounted near the antenna feed point.

The FC-10 provides a compact, easy-to-install unit that is styled to match the appearance of the Yaesu FT-840 (FT840, FT 840). For more demanding applications, the FC-800 uses specially selected thermally stable components and is housed in a waterproof casing to reliably withstand severe climatic extremes.

Both the FC-10 and FC-800 match a wide variety of antennas to within a 1.5:1 SWR on any amateur band frequency in typically less than 30 seconds. Transmitter power required for matching can be as little as 10 watts, and matching settings are automatically stored in memory for instant recall when the same frequency range is reselected later.
