[TowerTalk] Two questions (buried coax)

[wa5zup]

A SteppIR control cable sitting in water will degrade over time.  If it
develops any amount of inner conductor to ground leakage, it will take the
driver chips right out.
I went through that exact thing last year.  It was my stupid mistake.

FWIW, I had lots of water in a buried conduit for several months (without
knowing it).  Something prompted me to pull a rag through and it came out
soaked.  I connected a shopvac, in reverse mode, and blew a fountain of
water out the far end of the conduit.  I had three coax runs, one relay
control (5 wires), and one SteppIR control cable in the conduit.  AFAIK,
everything was working correctly despite of the water.  I just did not like
the idea of the cables lying in water indefinitely.  (Also, I could barely
pull a rag through the 2" conduit and could not remove or add another
cable.)  So I dug it up and replaced it with 4" conduit, with a better
slope, drain holes, etc, etc.

Did I need to do anything?  I don't know........maybe all would have worked
correctly indefinitely sitting in water in the conduit.
