Jim:
Install TWO four-inch conduits! (I say this with only a tiny bit of
jest.)
But if you have a choice, I'd go with the larger PVC. I think if you
do the math, you'll see that the price for a given area of conduit space
(12+ sqin in the case of one four incher) is lower for the entire system of
conduits (pipe, joints, fittings and especially labor, etc) if you use a
larger diameter conduit.
Besides, whatever it is that you calculate for the as-needed amounts of
2 inch conduit you will undoubtedly exceed in short order, unless you bury
extra consuit - there's that cost element again.
BOTTOM LINE: Go with the larger diameter conduit, even a second one if you
can afford it.

Subject: [TowerTalk] PVC size vs qty
I ran my coax on top of the ground as the initial installation and the
"hurry up" and get it on the air. I am now contemplating digging in the PVC
and replacing the original coax which has probably had some slight nicks at
least or damage from the yard tractor chains, etc.
The question is whether it is better to install a single 4 inch PVC or two
or more as needed of 2 or 2 1/2 inch PVC pipes.
Thanks,
Jim KG0KP
