So maybe you experienced tower constructors know all about this stuff, but
I am rebuilding my station at a new QTH and I have been quite worried about
getting RF out to an antenna 500 feet from the house. The run goes through
the woods with lots of gnawing creatures so I wanted to bury it and I
wanted it in conduit so I would never again have to trench through the
woods if I wanted to add another cable some day. I bought LMR 600DB and
was quite intimidated when the heavy roll of stiff cable was
delivered. But my excavating contractor said not to worry! Once he
realized that I was aware I would never be able to keep the conduit dry, he
suggested running the coax in 4" PVC sewer pipe (not "Schedule 40") because
of its lower cost for a large diameter pipe with a smooth interior. Since
no 90 degree "sweeps" are available, we pulled the cable before fitting the
right angle elbows at the ends. He bought a "Kellems Grip" for this
diameter cable from the local electrical supply house to attach my rope to
the coax and we pulled the coax, a control cable and a piece of 14 gauge
"pull wire" for use next time. Despite the impressive heft of the coax
roll, the job couldn't have gone easier. Although I had never used
anything except RG-213 before, I found installing the Times Microwave UHF
solder connections was fun.
The most impressive part was watching him saw(!) through a large rock
rather than move it or have a sharp bend in the pipe.
