You could get water in the cable if there is/are a crack/s or pinholes in the
jacked, and that doesn't have to be big. A corroded screen will cause
attenuation (and associated noise) and that will not show up with any simple
isolation test. Test the cable with an SWR meter. You check what SWR you get
with the other end open or shorted. Low SWR = cable attenuation. (That's how I
test my cable installations) The MFJ 269 has a built-in calculator for that.

Subject: [TowerTalk] RG6 coax question
Howdy Tower Talkers , My question is if water can get into the RG6 coax
through the outer cover ? The RG6 I'm using is Commscope but it's not
the flooded ! I lay the coax on the ground to a HI-Z Receive 4 SQ , so I
can remove it in the spring and reinstall in the Fall . The RG6-F-
connectors are 8 to 12 inches off the ground and taped good , so if
water is getting in, it would have to come in through the insulation ...
if that's possible ? I'm asking these questions because the HI-Z RX 4SQ
uses a Bias T throu the 4 phasing lines and if water or moister gets in
it will create noise and I have noise in 3 of the 4 directions ! 8.5
inches of rain in 2 days is allot of water !
Thanks Ed N5DG
