Hello All,

I thought I would throw in my suggestion for a good anti-seize for antenna use.  Jet-Lube has a product that is well suited for telescoping antenna parts, and for use on conductive surfaces. The product is Jet-Lube Silver Plus Regular, and it has a high aluminum content.  If you have ever bought an InovAntenna, you were supplied with that product to use during assembly.  I have been using it on my antennas for several years, and have had excellent results.  It also does not cause thee corrosion at exposed area of joints like the copper version of the Jet-Lube.

It is available in the USA through Amazon.

Engine heads is an interesting point. A lot of anti-seize is designed for very high temperature over 1000 F. Copper is said to perform well for that application. But we probably won't exceed 150 F in our application.

Bruce, you always make me think hard about stuff.    No code radio
licenses.   Post-open software licenses.   Now zinc vs copper
anti-sieze!   At least this time there are no lawyers involved :-)

I have experience with several New England antenna builders who
swear by Jet Lube SS-30 copper anti-sieze, and I have personally
disassembled 20m yagi elements that had been exposed to 7 years of
New England weather and they came apart just fine with no evidence
of corrosion.    But now that I think about it, the fact that it
had some kind of anti-sieze/anti corrosion grease applied was
probably the critical factor, with zinc or other fillers possibly
working just as well as or even better the copper.

Permatex explicitly recommends their copper based product for use
with spark plugs in aluminum heads, although I will concede that
there is not a lot of moisture involved in that specific application.

No matter what metal is in your anti-sieze, make sure to wear your
oldest work clothes when you use it ... that stuff gets everywhere
if you are even the slightest bit sloppy with it,  and it stains
your clothes permanently.
