That is a good question Tom. It would be interesting to know what effect
running an aluminum tube through the middle of one of these baluns is.
I know that aluminum does little or nothing to block electromagnetic
fields from nearby transformers, so I guess I was figuring the
interaction would be minimal, or at least a better option that strapping
the balun to the boom where all of the turns rest right up against the
metal boom. Again, that is just a guess and it would be interesting for
someone to actually measure the effects of the various mounting schemes.
I am using this mounting method on a Hy-Gain 155BA, CushCraft D-40, and
a Force 12 C-3E. All of these antennas appear to work fine with no ill
effects.
