Remember that a right-angle bend is best served by 2, 45 degree bends
with a short straight section between them. This will make pulling
cable much easier. A "pull-box" at corners is a good idea as well but
environment-resistant (not "proof", that's not possible!) pull-boxes
aren't cheap or easy to find.

Roger, just what is that white loamy stuff around the base of your tower
aside from ALL the coax? You need to show us a photo of the tower and
what you have hanging on it. It that sand that has blown up, opps, that
not sand. Your call tells me your in the northeast. So it must be
snnnnnow. I got COLD just looking at it. Have a nice warm day.

It t takes a good can to two cans to get a cable through my 4 inch
conduit now that it has so many cables in it. The yellow stuff is
easy to clean up

Roger,

If you are going to the trouble of using some kind of conduit, and assuming
it comes in 10 foot lengths, why not just push it through one piece at a
time? That is, push the coax through the pieces of pipe before you join the
pipes together. Besides, LMR400 is pretty stiff.

In my case I have 75 feet horizontal with two 45 bends at each end and
a 3 foot rise at the tower and 86 feet horizontal into the basement.
Getting more into that takes lots of soap and one hefty snake and it
still gets hung up at times.

There are (I'd have to go count to be sure now), 7 runs of LMR 400, 2
runs of RG-6 for the UHF TV antennas, One does everything cable to the
C/Ku band dish with rotor and polarization, two 3/8ths inch rotor
cable with one used for the rotor and the other for the remote antenna
switch.

With a single run of LMR 400 in 3/4 inch, I think pushing it through
one at a time would work fine. Although for no more than 20 or 30
feet...probably twice that you could easily push one run through the
full length. I'd guess you could push it through far longer runs than
that.
