[TowerTalk] burying cable

[john at kk9a.com]

Perhaps in some conditions it can push the cables up.  I had hundreds of
feet of Heliax and 4"pvc buried a foot deep in Illinois with no issues.
Deeper does have the advantage of making it less likely to accidently dig
into later, but trenching four feet or so deep can be quite a project.

As I sweat through digging (with a trencher and by hand) trenches putting
Commscope AVA7-50 hardline (eBay deal) and control lines from the shack to
a couple of towers here I mused on whether or not frost line has an
application to burying coax cable and low voltage control lines.

I get why one buries water pipes below the frost line as well as house
foundations, by why radio cables? Is frost heave an issue for cables if one
has some slack on either line of the line?
