One thing I found though is up here they sell a gray plastic conduit in a variety of sizes up to a several inches. It's much cheaper than that white PVC stuff, plus it has molded in connectors so they just snap together. I think I'm using stuff that's about 1.5"ID , and I have 2 of those all in 1 ribbon cables plus 2 regular RG6 cables going through it. It bends just enough to follow the contour of the ground a bit. Mine is on a slope, so I just have the low end terminate in a hole that's filled with leaves and covered with a rock. So the water drains out.
That conduit is pretty handy stuff. I even use a couple sections of it with a big tarp, to construct a tent over my pontoon boat in the winter. Also use it as bumpers on my dock, for the boat to bump into. Not quite stiff enough to mount a dish on though. A friend tried mounting a 10' dish on PVC, which didn't work. I once mounted a fixed Primestar dish on PVC, and that was OK. Next best stuff to duct tape.
