When I was a cable tech contractor I was told that you didn't need to bury a coax drop, you just needed to cover it. I have since learned that the guy who taught me had no idea what he was talking about. I am no longer a cable-guy but on Sunday a cable tech is coming out to replace my drop. I'm going to make him do it correctly or I'm going to complain to COX. So please, how deep does it need to be according to the NEC?
They'll more than likely bring a plow and simply cut it in and generally that is 10 or 12" deep in an orange smurf tube most likely.
If your going to be there anyway, leave them alone and let them do thier job.
Take note of where its routed (which wont be too hard to figure out for about the next 6 or 8 months till the grass grows back) and since your probably the only one who will be digging in your own yard anyway, remeber where it is and dont dig into it.
As long as it's not laying on top of the ground where you have to mow around it, who really cares ?
The less time they're there, the sooner you get your cable turned back on.
