Cleaning NMO mount
- Thread starter Red012

Take it apart, wire brush, wire wheel, hit it with ospro- phosphoric acid, kills rust. Wire wheel. Should turn rust black to carbon. Between parts apply silicone lube, re-install.
I put a hole in a coke cap and screwed it on the nmo soaked it in pb blaster and used a wire brush on it now it test good on the multi meter
Rust acts like a diode for RF which is not a good thing so you want that gone. I'd be inclined to assume water has got in the coax and I think I'd just bin the lot and install new mount and cable.
The cable is good i believe. I know it hasn’t leaked just external surface rust i cleaned the threads and the center nub they are clean now
Thats all thats left of it the tabs snapped off and my antenna fell over wasn’t getting any signal now i know why
The one I ordered to replace it is brass im also thinking about panel bonding a peice of sheet metal on the inside to brace the mount
