[TowerTalk] Nolux or not-to-nolux

[JC Smith]

Butternut (the vertical, not the coffee) had some stuff called
Butter-its-not (or something like that) that was specifically for that
purpose.  I have purchased it in the past from ham vendors.  The stuff I see
most often is Ox-Gard by Gardner Bender (GB).  Almost any hardware store
should have that in the electrical tools section.  Look for the red blister
packs.  Then there's Noalox and Penetrox.  I can't remember who makes them
but you'll probably have to go to an electrical supply to find them.  I
think these all do about the same thing, but if anyone has had particularly
good or bad experience with any of them, I'd like to hear about it.

I highly recommend you use one of these products.  On FD last year we were
having trouble getting a HyGain DX-77 to load up correctly.  We checked each
joint with an ohm meter and sure enough one section was corroded badly
enough that there was high impedance across the joint despite the fact that
the antenna still looked new and shiny.  The antenna had been assembled
without anything on the joints.  We reassembled it with Ox-Gard and it
worked fine.

That is the question.

I'm putting up an elevated 80M vertical using old Heights tower sections.  I
intend to load the thing on 80M and want good conductivity in the joints of
the tower.

There are many products out there.  None of the typical vendors appear to be
hawking the stuff on their websites.

#1 it is supposed to keep the aluminum unexposed to air.
#2 it is supposed to be conductive to facilitate a good RF connection

What to use and where to get it.  Anybody got good info on this?
