[Moon-net] Damp cable help...

[Jordan]

Hi John...Yes, the center conductor is a pressure fit contact ... It seems 
that the best solution is to remove a few inches of each end ,check for 
corrosion replug and re-test...

The run is actually about 80 feet horizontal, and then another 20 feet up 
onto the roof.....73...Jordan....
