The rule of thumb is to use a conduit diameter that's twice the diameter of
the cables. Your two coax runs together are 1". I don't know the diameter of
Channel Master cable, but if it's close to 1/2", you need 3" conduit. If
it's close to 1/4", then you may be able to get away with 2.5" conduit. I
wouldn't go with less than that.

Subject: [TowerTalk] Conduit size?
I'm planning to run about 70ft of conduit to service two RG213 (or Bury
Flex) runs and a single Channel Master 3 conductor control wire. It will be
a straight run with 90 degree sweeps at both ends.
I'm planning on moving from this house in 2 years and really don't plan on
investing more on antennas here so additional runs aren't really an issue.
Will 1.5" electrical PVC be adequate to handle this or do I need to go to
2"?
thanks
