The manual antenna tuner 80 to 10 meters is capable of, what I believe, at least 5 kilowatts. By looking at the variable capacitors and the inductor, it is definitely a high power handling manual antenna tuner, possibly handles more than 5 Kw.. It has an added SWR meter and sensor that works. It also has what looks like a 4:1 bulan. but not sure. I did not test the bulan. There is no cover with this unit. I believe it was in a rack mount when in operation. The antenna tuner is as is, guaranteed to work, but not sure if the balun works. It looks like it should but no guarantee with the balun.
