Topband: Beverage Crossing Buried Powerline

[rfman45]

I'm rerouting and burying many of my beverage coax lines but two will have to cross a  buried (2-3 ft deep) 220 line. Apart from the issue of hitting the line while digging which I'm well aware of could the buried coax cross this relatively shallow entrance service without ill effects? I realize that this is not ideal. Alternatively I suppose I could have it come above ground to cross the line and then go underground again.
 
I would appreciate any thoughts on this matter. Thank you in advance for your consideration.
