[TowerTalk] Belden 9913 concerns

I would not use this coax for your application.   Any nick or open 
connection can cause the cable to fill with water.  Belden 8267 is more 
durable as well as many other solid dielectric cables.

Hello all,

I'm back on Towertalk after an extended absence. A year
or so ago, I bought a 500' spool of Belden 9913 (not the
flexible type) and it has been sitting in my basement, with
the plastic shrink-wrap still on it.

I originally bought this coax to install in an underground
PVC conduit that runs from the house to a tower in the
"side yard" but have heard some "horror stories" in regards
to the use of this coax.

I have heard that this coax will pick up moisture just by
sitting around (as in my case), which renders the coax
useless. I did run a dehumidifier in the summer in my
basement but I'm sure the humidity level was not all
that low.

Also, now that I think about it, I'm having second thoughts
about installing it in my underground PVC conduit, as
there will be moisture (standing water) in parts of the con-
duit, as there always is in conduits that run underground.

I have provided some PVC boxes for water drainage in the
conduit system and all of the conduit fittings are also PVC.
I'm quite confident that I can install the coax in the con-
duit without nicking the jacket but I'm still concerned about
this proposed installation.

Any comments or suggestions will be appreciated.
