My own experience is that, once there's a breach in the plastic
sheathing, water leaches up and down the entire braid, eventually
rendering the coax useless. I've taped some up and it still seems to be
working, but I've also had major contest disappointment when a whole
tower of antennas proved disconnected from bad coax braid.
One test is to measure the electrical resistance of the center and the
braid from end to end, comparing it to known good cable.

For the past 4 months I have been denuding my hilltop from 30 years
growth of Poison Ivy/Sumac/Oak, Thorn Bushes of all types and thousands
of saplings. In the process I have been discovering old coax, some of
it in possibly re-useable and some of it ready for the landfill.
Questions:
1) I have heard people say that it can be taken to the scrapyard. With
Copper ~ $5 / lb, is there any correlation to how much 1000' of old
RG213 might be worth as scrap?
2) Can old coax be recycled as ground radials or elevated radials for
verticals, 4-squares, etc? Does it need to be stripped to the Center
Conductor or can it be connected to the cc or the braid? Does it matter
whether the cc or the braid is connected to ground?
3) For Coax currently in service that has cuts in the PVC cover with
some of the braid showing, does this need to be cut away and replaced or
can it simply be taped over and then continue to be used?
4) I also have old 3 and 5 conductor unshielded cables in use outside
that have had the white outside covering abraded and with some of the
colored wire insulation showing.
Any idea what this might be worth at the scrapyard per 100'?
Can this be used as radial wire?
Tnx & 73
Bob, KQ2M
