It would probably work however Belden 9913 is a poor coax choice for outdoor
use. I too have had water pour out of it. I threw all of mine away decades
ago and I would suggest you do the same.

Hi Folks,
A few years back some 9913 I was using apparently got water in the coax. I
say this because of fluctuating SWR issues and I noted the shield when cut
into was almost 'black'. So for my minor purpose of using spare coax for my
dump power on an 80 meter 4-square can some of this coax be used? When I
scrap the shield after exposing it with a knife will reveal the shinny
copper again so is that sufficient to use some for reading dump power on my
wattmeter at the shack? Seems if I try and get readings like what I had with
the LMR-400 then it could be used. Coax is so expensive these days I want to
use my valuable LMR-400 elsewhere if possible. And having a convenient way
of reading dump power is of course important too.
