I did my satellite dish that way in 1985 and have had no problems. You'll need a 90 degree elbow at each end. Use the largest radius you can get away with. To the OP: A sweep elbow is that "large radius" section. Sweep elbows are available in various large radii, like 36", and will treat your Heliax or other cable bends kindly. The plumbing trades use them, too. This picture shows a half-buried sweep elbow http://sugarmtnfarm.com/blog/uploade...GElectPedestal OpenT6799w.jpg It's from http://sugarmtnfarm.com/blog/2009/08...-electric.html The article may provide the OP some tips. RELATED: With my dish install, I picked too-small PVC and couldn't pull the whole length. I had to cut the PVC into sections, pull the conduit through each section (and through new couplings) and then glue the sections back together. My mistake wasted half a day. Check your "pull-ability" before gluing your parts into a unit. Sal |

The plumbing trades use them, too. I've often thought I would try a 45 degree elbow, and then a straight section of pipe coming out of the ground at an angle. That makes it much easier to pull but does look a bit odd. It also has the advantage that I might be able to use some manner of power assist to pull the cables through the conduit. Pulling on a 90 degree elbow is a sure way of breaking it. 45 degrees can be handled with a pully or careful positioning of the winch. Disclaimer: I've never done this so beware of surprises.

Check your "pull-ability" before gluing your parts into a unit. One tower owner had a 90 degree elbow projecting out of the ground near the outside of the concrete tower pad. He tried to pull the entire cable bundle through at one time with a winch hooked to a pully on the tower from above. Instead, he pulled the 90 degree elbow and about 10ft of pipe out of the ground. I didn't see it happen but was involved in the subsequent cleanup job. Moral: Don't let the cable bundle get twisted as it enters the conduit or it will develop a "lump" and jam. Tower drivel: http://www.agl-mag.com It's totally for commerical tower owners, doesn't have anything on construction, is stuffed with tower politics, but does make interesting reading.
