How far away must electric wires (110V) be kept away from coax and ribbon cable with coax for satellite reception??? I dug a ditch about 2' deep to bury my cables running from my house to my satellite dishes. A freind has his just under the soil but I want mine deeper so I do not hit them with anything. The cables are in plastic conduit to protect from rocks and metal debris from a old barn that once stood. I want 110V power near my dishes for when I am working and testing out there without running extension cords. (It is well over 200' from my house!) I heard that if the power and coax cables run parallel of each other a certain distance should be maintained to avoid interference. Someone else I know has their coax for their Dish Network strapped to the main electric service wires on the house and they get no interference! It is a 2 story house and they run about 15' together! I want to make sure before I place the electric cable and bury them all that I will not get interference. The coax is already there in conduit as I mentioned before.
