[AMRadio] coax lead in

[Rick]

Thanks, Rob. I like to do things as close to right as possible the first
time around, but I'm afraid my budget, age and want to won't allow me to go
that far. HI

You can't fight mother nature.  You have to play along.  sealing pipe
to keep water out, steel wool etc. won't do anything except keep you
fixing the line all the time.   If you have to go under a driveway,
you have to allow for drainage and keep the passage open for
evaporation.   You have to excavate on each side of the driveway and
cut a trench through it and lay corrugated galvanized steel conduit
about 12 inches diameter down in the trench.  It should have gravel
around it.  to the ceiling of the conduit you have to attach a pipe
that's about twice the diameter of the feedline.   lay the whole thing
in the trench so the ends protrude a bit past the pavement above, and
with a slight pitch to one end to drain into the excavated area.  Fill
in the trench and pave over the top.   Push your feedline through the
pipe.   Animals may still chew on it, maybe not, but the whole thing
will drain, there will be no moisture problem because it is an open
system and the feedline will be easy to get to, and examine.   This is
laborious and expensive but that is usually how it is if you want to
do something right and not have to continually mess around with it.
Use LDF4-50 and animals may leave it alone more often.  I run LDF4-50
and simply lay it on the ground.  It eventually sinks into the grass.
I have done that for years and never had any animal damage and we have
you name it, moles, skunks, chipmunks, groundhogs, possum, deer,
geese, squirrels....
