这一款不知是否适配ft-897d？可调范围多宽。
the yaesu fc-40 antenna tuner is designed for the ft-857d and ft-897d. it uses of the control circuitry built into the ft-857/897, which allows the operator to control and monitor automatic operation of the fc-40 mounted near the antenna feed point. for demanding applications, the fc-40 uses specially selected thermally stable components and is housed in a waterproof casing to reliably withstand severe climatic extremes. the fc-40 matches a wide variety of antennas to within a 2:1 swr on any amateur band (160 through 6 meters) in less than 30 seconds. and hook-up couldn't be easier. transmitter power required for matching can be as little as 4 to 60 watts, and matching settings are automatically stored in memory for instant recall when the same frequency range is reselected later.
