[TowerTalk] Corrosion-proofing coax connections

[Mark .]

Tony

<< Checked an old PL259 connector and noticed some corrosion on the center 
pin.
I was surprised since the connector was packed with "Stuff". Is there a 
better non-conducting anti-corrosion RF connector grease out there? 
Preferably, something I can find at Home Depot?

Hi Tony,

Sounds like you're referring to the product called 'Stuf' sold specifically 
for RF connectors at a hefty price. I'm surprised that corrosion developed 
in your connector. How long has it been in the weather, and did you also 
coat the center pin on the PL-259 before assembly?

This material appears to be identical to 'dielectric grease' or 'spark plug 
boot grease', which is available in tubes very inexpensively at auto parts 
stores. This is a thick silicone grease made specifically for keeping 
moisture out of connectors.

I use PL-259 connectors on my mobile HF antennas at the feedpoint, under the 
bumpers. The dielectric grease does a great job of keeping these clean. I 
wouldn't recommend the usual antioxidant pastes, such as NoAlox or Ox guard, 
since these may possibly create a conductive path between the center pin and 
shell.
