[TowerTalk] Burying hardline question

[Ray]

Is is OK to direct bury Andrew's 7/8" and/or CATV 75 ohm hardline? 
 
I do have gophers in the area and don't know first, if hardline can be
direct buried, and second, if the gophers will chew on the outside covering
material. If they do, I don't think they can get through the outer copper or
aluminum shield, but it would open a path for water intrusion.
 
Tnx,
