What type of coax to use for underground cable runs? (1 Viewer)

[Travis Olson]

I'm going to be hooking up a DirectTV dish about 75 feet from the house. I'm going to be burying the cable. What type should I use for this? Is there a special kind?

Unless it's a trick question, yes, underground approved coax. It needs to have a non-pourous exterior cover to be moisture resistant, and I doubt all coaxes qualify for that, though in reality most coax is probably fairly moisture resistant. But to be sure, you should use coax similar RG-6 to what the cable companies use. Though I hesitate to say that, because much of their coax is copper coated steel conductors for strength, not optimized for picture quality. But it is underground approved.

You might go to the Belden web site and see if any of their cable is underground approved.

You want something like this – rated for direct burial.
