[TowerTalk] Re: Summary: Buried Pipe for Cables -- Further Questions Please?

[Guy Olinger, K2AV]

Water will always get into the pipe. During really wet times, the pipe
may actually fill up. It may just happen over a period due to
condensation inside the pipe. The coax, wire, (and pull rope) you use
STILL needs to be the buriable (inert flooded) type to keep water from
doing damage.

What you don't want to have happen: The first spring the pipe fills
completely up with water and stays that way. The first winter the ground
around AND the water freeze. Pipe is split and coax is crushed.
