I agree with Bill.
Bury-Flex is advertised as being suitable for direct burial. I have 4 runs
of over 100' that have been in the ground for 9 years, with no apparent ill
effects.
On the other hand, Larry is worried about something (a shovel or whatever)
damaging the coax. To the extent that this is a problem then plastic pipe
makes sense.
Since Bury-Flex is rated for direct burial I don't think I would worry too
much about moisture in the pipe, particularly if I could get a little bit of
slope on the pipe. Someone mentioned the 4" perforated irrigation tubing
and this would also be a good choice, although the burial trench would have
to be larger.

Why not skip the pipe (protection from shovels aside) and simply bury
the Bury Flex.? Same trench less work and flooding issues.
I know all the reasons for the PVC but Simple works too.
