I recently took down a 130 Rohn 45G tower, 4 element 20 meter Hy-Gain 204BA
and a Hy-Gain 10/15 Duo-bander. The antennas were installed sometime in
1975 (30 years). I used all SS hardware and Ox-Guard on the Aluminum
elements. The antennas were painted with a mixture of varnish and Thomson's
water seal. The antennas are still in very good shape. The varnish & water
seal had completely disappeared. Go ahead and use your good common sense.

Subject: [TowerTalk] Corrosion proofing Elements/connections
All,
What's the best way to protect electrical connections from corrosion? I have
new antennas going up and would like keep the balun connections corrosion
free as long as possible.
Since there are two different metals involved with the driven element /
balun connection (stailess nuts, bolts and aluminum elements) is Penetrox
the best thing to use? I was thinking of Penetrox and then a liquid tape or
Scotchkote on the balun connections.
I was also thinking about coating the balun housing and balun wire with
something to keep UV from taking it's toll?
On the element joints -- is it best to use Noalox or Penetrox? It seems both
would keep connections corrosion free and do the same job with conductivity.
Is there a difference?
Has anyone taken apart Yagi elements after 5 or 10 years and noticed if the
Noalox or Penetrox stopped corrosion from forming?
Thanks,
Tony KT2Q
