I had RG58 in 'moisture' for a decade: in fact 70 metres at the bottom
of a pond! Everybody said, that it won't work, but I didn't notice any
problems. But I had them on the part, which was on the ground: hares bit
it broke and 3 years ago I replaced it with a better one: Tri-Lan RF240.
It wasn't cheap for almost 300 metres feed, but I think it will last as
long as ... Now I buried it carefully a few cm also on the ground. I
think all is well as long as the shield doesn't get breaks.
Getting a length of coax inside a garden hose isn't as easy as it may
sound, I tried. Some length goes easy, but in the end one needs to put
first a string with air pressure. I am glad, that I didn't take the trouble.
Best regards,
Mauno

Haven't seen any response to this, James, and am probably not going to
be much help.
I've just used RG58 variants for up to 100' in permanent installations
around the yard, 10 to15 years in some cases. One of them runs
through about 70' of rigid PVC electrical conduit IPEX #032907 and is
buried. Mind you, I've heard that although such conduit will keep
the groundwater away from the coax, water vapor will condense inside,
leading to a wet interior anyway. That coax still seems to work,so
maybe it's dry...or maybe not.
On DXpeditions, I've run over 500' of RG58 coax to DKaz'es and such,
and not suffered particularly.
best wishes,
Nick

I am curious as to what type of coax everyone uses for DKAZ antennas and
also general international shortwave band listening dipoles?
It's time to revamp my antennas and I want to use the right cable
that will
last for a while.
I have read that RG-8U is good for long runs of a 100 to 150 feet,
and if I
was to bury my coax, which is the best pipe/conduit to use to bring my
cables into the shack?
