[Antennas] Old Coax

Thu, 12 Sep 2002 08:55:08 -0700 (PDT)

Larry,

Most of the issues with coax relate to water getting
into it and causing losses and other problems.  After
having coax up for a few years if you look at it you
will often see a white powder around the braid,
indicating that water has gotten into the line.  Water
is an insidious beast that eventually gets in to
exposed coax.  I recommend using LMR400, espscially if
you are planning to bury the coax.

Hope this helps.
