The FC-40 is a microprocessor controlled antenna tuner unit designed for the FT-897/857 series of transceivers. It makes use of the control circuitry built into the transceiver and allows control and automatic operation. The FC-40 is designed to match a wide variety of antennas to within 2:1 SWR on any amateur band (160m to 6m), typically in less than 10 seconds. Transmitting power required for matching may be as little as 4 - 60W, and matching settings are automatically stored in memory for instant recall, if the same frequency range is selected later. Mounted near to the antenna feedpoint, it is housed in a waterproof case capable of withstanding severe environmental conditions with high reliability

- FC-40 ATU Multi-Band Success
- This ATU appears to like short antenna lengths under 45 feet however I had complete success on all bands from 160 to 10 meters using a 72 foot long wire, 4:1 unun and good ground. My feed line is the original 16' coax to a 1:1 Balun then an additional 50' of RG213 to the tuner. I used a 75' CAT5 cable and purchased additional connectors for the control cable to match the tuner (soldering the cable is not for the novice).
