I've decided to have my dish installed on a pole mount in my backyard, about 75 ft from the house. I want to run eight RG6 cables buried underground. However I haven't found a lot of explaining (even on this web site) about how to get this done. - Do I need to buy a conduit pipe for the cables...

The house that I'm having built is like the one in the picture above. As you can see, the person had the dish installed on the roof with 4 wires getting in under the roof (back of the house). I'm affraid it could eventually damage the roof. I'd rather have mine put on the side of the house...
