Connector kit for AT-120 tuner

This kit provides two four-pin plugs designed for the ICOM AT-120 antenna tuner. It suits radio operators building or repairing the control cable between the tuner and a compatible transceiver. The plastic housings arrive ready for soldering or crimping. Buyers needing a different pin count or a waterproof shell will not find it here.

Thermals and power draw

The connectors carry only low-voltage control signals, so they generate no measurable heat during normal operation. No fan or heatsink is involved and the parts add no audible noise to the station. Power consumption is limited to the tiny current drawn by the tuner's relay coils.

Questions about this item

How do I install the 4-pin connector kit on the ICOM AT-120?

Solder each wire to the correct pin on the supplied plug, then insert the plug into the AT-120 tuner socket until it clicks. The step often missed is matching the wire colours to the pin-out diagram before soldering.

What maintenance will the connector kit need after installation?

Inspect the solder joints and plug housing periodically for corrosion or loosening caused by vibration; re-solder any cracked joints and reseat the plug if it becomes intermittent.
