The KAT500 is a new high power autotuner that can be used with both the K3/KPA500 and all other HF amplifiers and transceivers. The KAT500 uses the same topology and high performance tuning algorithms as the popular 100W autotuner in the K3. Typical matching range at 500 W is up to 10:1 on most bands. (slightly less on 160m and 6M). This also equates to a range of 3:1 for higher power levels, up to 1000 W.


The KAT500 has a front panel SWR display and three selectable antenna outputs. It is the same width and depth as the K3 and the KPA500, and it is just 1.5" high



- Frequency/Typical Matching Range and Power Limit

3 - 30 MHz:

600W into 5 to 500 Ohms (10:1 SWR)

1000W into 16 to 150 Ohms (3:1 SWR )

1.8 - 2MHz:

600W into 10 to 500 Ohms (5:1 Low Impedance, 10:1 High Impedance SWR)

1000W into 16 to 150 Ohms (3:1 SWR )

30 - 60MHz: 500W into 5:1 SWR (10 to 250 Ohms)

- Matching specified to a 1.0:1 to 1.6:1 resultant SWR. Power rating is ICAS (Intermittent Commercial and Amateur Service).

- Autotune Power Range: 10W Ñ100W For better matching accuracy, tune with >20W.

- Selectable Antenna Outputs: 3

- Weight: 4.6 pounds ( 2.1 kg )
