[TowerTalk] Corrosion proofing Elements/connections

[KT2Q]

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
