Use the length,
At the far end put it into a dummy load.
Put your watt meter at the transmitter, make say 100 watts,
move watt meter to the dummy load and see how many watts are there.
Thats the losses.

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.
