U20377 Used Kenwood AT-230 Antenna Tuner

Overall Condition: Used, good physical condition overall! Cabinet State: The outer metal enclosure exhibits general surface scuffs and handling marks on top and side covers, typical of desktop station use and age. Front Panel & Controls: All control dials (R TUNE, X TUNE, BAND, and ANTENNA selector), push switches (200W/20W, FWD/REF, POWER/SWR, CAL), calibration control, and backlit analog meter are fully functional. Rear Connections: Rear panel SO-239 coax connectors (INPUT, ANT 1, ANT 2, DUMMY LOAD), wire terminal (ANT 3), and wing-nut ground post (GND) are clean and intact.

The Kenwood AT-230 is a classic, heavy-duty manual HF antenna tuner engineered to match the styling of Kenwood’s legendary TS-830S, TS-530S, and TS-130S transceiver series. Covering 1.8 to 30 MHz across 9 HF amateur radio bands, it features a built-in antenna coupler, an inline dual-range RF wattmeter (20W / 200W), an SWR bridge, and a multi-position antenna switch.

Capable of handling up to 200 Watts max feed-through power, the AT-230 allows operators to switch between up to three coax-fed antennas, a random wire antenna, or an external dummy load. Its internal matching network also acts as a band-pass filter to reduce TVI and unwanted harmonic emissions.
