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.
 
 
 If you do not parallel the line and bundle with the line, you are fine.  The 
only possible problem might be lightning, which could flow between the 
shield and the 240 line. That issue happens anytime a feedline crosses 
almost anything metal, even a  fence or pipe.

All good topband ops know how to put up a beverage at night.
