Most CC owners I know used stainless when assembling those antennas and the
factory followed suit decades ago.
Id say Hi-Gain was a prime example of intermittents waiting to happen. In
the traps, the single point element compression screw or the sheet metal
screw attaching the Beta Match to the boom. And good luck to anyone using
the provided BN-86 balun at over about 800-1000W. Id hate to try and count
the number of TH-6's and others Ive helped take down for rebuilding or
simply selling off. Ive got parts of 3 of them out in the woods, used the
booms and some element material for HB monobanders.
