Years and years ago, I headed enginering for a company that owned dozens of 
cable and MATV systems. Because of FCC regulations and proximity of some 
systems to airport flight paths, we tested a variety of things to reduce 
connector problems.

We very quickly abandoned things like noalox and settled on either 100% pure 
GE silicon dielectric compound, or a Teflon based dielectric compound 
manufactured by a company in Lorain Ohio (or some city close to Lorain). We 
actually found an increase in connection problems with things like Noalox.

Our policy evolved into dabbing the male connector inside with dielectric 
compound, and lightly smearing the female threads. We used the Teflon paste 
only on trunk lines.

Noalox caused center pin connection problems on our trunk and drop cables, 
turning copper black. We had to replace many connectors that had Noalox 
contacting the copper. I think it was some sort of zinc-copper reaction, but 
that was years ago.
