We usually attach 6-8' to the silo, which gives you about 15' above and clears the dome nicely.

One silo we did use a 21' pipe and it still does not clear the dome. How much pipe to attach to the silo, so how far above the concrete do you get? Bill Gaylord wrote: We do the same thing, but we use the full 21' galvanized pipes from the hardware store. I secure them with hose 2 hose clamps around at least 4 of the steel rings. I did not want to screw into the concrete, as I was concerned with the screws being able to come loose. With hose clamps around the steel rings, nothing can wiggle loose. We have been doing this for 5 years now and have yet to have a single hose clamp break. Hose clamps are also stainless steel, so rusting is not an issue. Bill Gaylord, President COLI Inc.

Attach pipe with L brackets (Old ARC Antenna mounts) to the silo with RedHeads (concrete anchors) into the concrete. Push up pole, with usually about 6' remaining (attached) on the silo and 8-10' sticking above the cap. I get the pipe from a local fencing and hardware company. They have it in 20' sections usually. Used to us 30' push up poles, but they bend too easily.

Several of them are old concrete silos with metal domes. The top of the dome is more than 10' above the top of the concrete. I have been mounting with 10' pipe on the ladder side and not servicing customers on the "back" side. It has also worked out that the backhauls are on the ladder side as well. This year the trees seem to be growing a lot more leaves than in the past. I have a couple of silos that I need to get the backhaul higher than the 10' mast will allow. If I can get above the dome, I could also increase the covereage area. So, the question is, for those of you using silos, how to you get above the dome? -- Scott Reed Sr. Systems Engineer GAB Midwest 1-800-363-1544 x2241 1-260-827-2241 Cell: 260-273-7239 ------------------------------------------------------------------------ -------- WISPA Wants You!
