Overview
The ATU option (KHATU1) greatly enhances the KH1’s versatility. It includes:
- an automatic antenna tuner unit (ATU) that works with both the BNC jack and whip
- internal whip-matching network for use on 20/17/15 meters (30 m at higher SWR / lower power)
- telescoping whip, plus two clips that retain the whip on the side of the KH1 when not in use
- 13’ counterpoise wire suitable for 30-15 m use (with the ATU)
