After 20 years of use I sent a Ham II to HyGain. For $75.00 they completely
overhauled the unit & even replaced the outside castings with new ones. For
nominal fee they eliminated the 8 screw board with the latest plug-type
I too have a spare Ham IV rotator which I sent in & got the same results.
It's ONLY HyGain, as far as my experience tells me!
