True. At 800Mhz it read as a 14dB return loss bump ( 1.5:1 VSWR)

Yes, here is a product called STUF. Look at:
http://www.wavehunter.com/
and look for informaton for "Stuf Dielectric WaterProofing Filler"
My company tried this product on an 800MHZ system with terrible results. Poor
return loss readings, loose connectors after time, were some of the problems.
Use properly installed type-N connectors, then seal. I have undone
connectors that have been properly installed and used in an ocean front
environment for 20 years. The connectors are as bright and clean as the day
they were installed.

Yes, proper weatherproofing on the outside. If you are getting corrosion
on the inside, your weatherproofing has failed. However, by their poor
design, some antennas cannot be properly weatherproofed at the point of
attachment. This is typical of many ham-grade antennas.

Kerry,
Although it is a good idea to apply a very small amount of silicone
compound to the threads of a connector, one must be careful to not let
any of the compound get on the electrical contacts. One of the primary
reasons for using type N connectors on antennas is that they are
watertight when
I've seen the silicon paste that used to be called
tuner lub in connectors. The main thing is to keep
the water out in the first place by using the correct
water proofing material. It is very sticking and hard
to get off but works. Paul kb9wlc

Is there anything that can be
applied to the inside of an antenna connection to prevent corrosion and
oxidation?Kerry - WA2NAN - [EMAIL PROTECTED]
