FC-800Automatic antenna Tunerfor the FT-890 TransceiverThe FC-800 is a microprocessor-controlled antenna impedance matching networkdesigned to provide all-amateur-band transmitting capability with the FT-890 HFtransceiver and an end-fed random wire or long whip antenna (the FT-890 internalantenna tuner should be used with antennas requiring coaxial feedline,such as beams).The FC-800 makes use of the control circuitry built into the FT-890,which allows theoperator to control and monitor automatic operation of the FC-800,mounted near theantenna feedpoint.The FC-800 uses specially selected thermally stable componentsand is housed in a waterproof casing to reliably withstand severe climatic extremes.A carefully chosen combination of solid-state switching components and high-speed relays allows the FC-800 to match a wide variety of antennas to within a 1.5:1SWR on any amateur band frequency in typically less than 3 seconds.Transmitterpower required for matching can be as little as 10 watts,and matching settings areautomatically stored in memory for instant recall when the same frequency range isreselected later.This manual describes base and mobile installation and operation of the FC-800 withvarious types of antennas.SpecificationsOperating frequency range:1.8-30 MHz with 12-m+end-fed wire,3.5-30 MHz with 2.6-m whipMatching impedance:50 ohms (unbalanced)Maximum transmitter power:150-W PEPMaximum SWR after tuning:1.5:1 or better (if antenna is not a multiple of)Required RF power for tuning:10±3WTuning time:3 seconds typical,10 seconds maximumPower supply:13.5-V DC+15%@700 mA (from jack on FT-890)Operating temperature range:-30to+65℃(-22to+149℉)Case size (WHD):264×80x264mmWeight:2.1kgSupplied AccessoriesCoaxial Cable(5m),p/n T9101366Control Cable,4-wire(5m),p/n T9101419CPage 1
