If your CATV hardline has a vinyl type covering you shouldn't have any
difficulty.  I had the unprotected =BD inch variety buried for over four
years without problems. but let me relate a story told me by the Cable
TV folks.  They had a run that went under the roadway of a bridge over a
swampy river, and used the uncovered stuff.  The corrosive action of the
water etc. caused the shield to break down in less than a year and they
had to replace it with something more impervious.  =

If you have a sufficient amount of hardline, I'd recommend a second run
as a spare.  I did that and, because I hit the hardline with a mower
where it exited the ground to the tower, I ended up using the spare.

Good luck... =
