KAT2 Automatic Antenna Tuner

The KAT2 allows you to connect nearly any antenna directly to the K2 and use it on all bands (160-10 m). Two antenna jacks are provided--instantly A/B test both antennas on any signal using the ANT 1/2 switch. Uses all latching relays, so current drain is zero except when tuning.
