[Antennas] Anti-Corrosion Compound

[Chris Boone]

Some folks emailed me direct about the recommendations I posted..Let me
clarify:
 Silicon vs Silicone.....I should have said silicon based thread
anti-seizures...especially those with graphite or Teflon in them...use them
SPARINGLY on the THREADs only..Do not flood the connector....You have NO
idea on the power rating...(Broadcast folks run MORE than 2KW into their
lines in a lot of instances but not all)...and if the connector is flooded,
what doesn't conduct at 100w may flash over or conduct at 1KW or more..NEVER
trust any flooded connector in RF environment..if you do, it will bite you
one day! Again, NEVER flood a RF conductor...it will come back on
you...(been there, got the burned connector)

Some silicone is not acidic...that still does not mean it is safe to use on
coax around RF....Again, do NOT put anything in the center of a RF
connector..use a THIN layer of an anti sieze preferably on the female
threads only...do not allow it to reach the center conductor...unless you
want an issue down the road.

I have never used anything on the inside of a connector...but using the
rubber tape and Dux/Duct/Coax seal and it covered with another layer of UV
resistant tape will give you decades of trouble-free operation...and IF you
need to open it, it will look as it did on the day you installed it..
