[Moon-net] Damp cable help...

[John Lemay]

Hi Jordan

I wonder if you have asked yourself how water got into the shack end of your
cable ? I'd be worried !

The nature of the dielectric in Andrews Heliax seems to allow water to
travel a limited amount, so it might be wise to cut off 100mm of cable and
re-terminate it.

For the record, plugs for LDF4-50 have a solder connection for the inner
pin, LDF5-50 has a push-fit or screw-on (can't remember which).

Regards

John G4ZTR

Well, after a nice BBQ'd steak and potatoes, I decided to bring the cable 
end down  and get the connector apart , and it worked.... Problem is, no 
moisture whatsoever, but I did learn that the connectors for the LDF4.5-50 
cable uses a press fit captive center conductor.
Seeing as the only other connector left to check in the entire system is the

shack end of the 4.5-50 cable.
When I opened the connector at the shack end, sure enough there was maybe 
5ml of water inside... Now to clean things up and get the cable back 
together before it's too dark to see out there... 73...Jordan.....
