The voltage or current can be as bad as the 1:1 voltage or current multiplied by the square root of SWR – NOT multiplied by directly by SWR. So voltage or current at a 6:1 SWR could be as bad as about 2.5 times the 1:1 SWR voltage or current, and at 10:1 SWR a little over three times the 1:1 S

Ed - I think you are confusing the power handling capability of a tuner with it's ability to match a non-50 ohm load. A tuner may be able to match a highly reactive load at low power, but be totally unable to handle the same load at higher power levels. The match involves selecting the appro

Hello, I'm trying to understand what the KAT500 power limits mean in real life. If I am tuning an antenna that initially shows a very high SWR (say 14:1), and I am using high power (say 1000 watts out), the KAT500 is going to open up the PTT line, and the tuning operation will take place with
