His reasoning was that enough bare aluminum-to-aluminum surface area
would remain that the use of the Permatex was very unlikely to negatively
effect antenna performance. Anyone have an opinion on this? Should I
re-do
the joints in question while the antenna is still on the ground? Or would
this be a needless exercise at this point?
I've used Blackburn compound for over thirty years. A nasty, sticky graphite
mixture, it keeps new or cleaned aluminum joints like new after years in
service. When I was just getting into the hobby I salvaged an old TH-4 and
on the recommendation of a couple HAMs who had been at it a few years
drilled and Zip screwed each element piece to make the mechanical -
electrical bond.
