Went around and around with my installer yesterday about how and where to mount the dish for the HR20! He was determined to mount it on roof, I wanted it on tower, he said no, to flimsy and no solid way to mount dish ! Then we decided on compromise and went for the chimney, but I had to get a bracket made for us to do that, which will take a few days to do! Got to thinking if this bracket will allow mounting dish to chimney why not tower as well? Contacted installer to ask if we could do that and he said no because he was afraid wind would move tower and that's a no no for this Ka band! After talking for some time about this he gave in and said we would try it on the tower but if wind was a problem then it would have to be moved to chimney! This dish will be mounted about 15 feet up on tower just above roof line, the tower is Rohn 20 and mounted in concrete, does anyone out there think that I will indeed have an issue with wind? This bracket will be a plate with a piece of 1-7/8" pipe coming out of the center of plate and then turning up to mount dish to, plate will be clamped to tower with 4 pipe clamps! Just realized I may have posted this in the wrong place!!
