I think what you are referring to are scaffold clamps. We use them in those big pipe scaffolds that masons/workers use in building construction. Basically they are two/hinged/ clamps. Each of these h
I've built a House bracket that will support a US MA type or Wilson Type tower to a house while retaining full rotation. It's cheap but simple to build. I can supply photos upon request. It uses a 's
I got so many requests. Wow. As there are a bunch of pictures, I created a Zip file to speed delivery. It can be downloaded at: http://www.files.billnjudy.com/Bracket.zip The circular rim is a 'mini
As a retired Chicago licensed contractor, I can speak with some practical knowledge. DO NOT allow rebar to contact the earth. Moisture will rust the bar in incredible time. Rust can expand and produc
A rebar cage sitting on gravel at the base of the hole is the same as sitting on the dirt. Moisture, seepage, that's what we want to protect the rebar from. Gravel is suggested for tubular tower base
I bought one, and it died within weeks. When I called them about the warranty, they said that rating is for a 'horizontal' pulling load and not a vertical lift. Grainger would not stand behind it. I

Real simple and no equipment or math needed. If the anchors are to be 80 feet from the tower, try this. Build an 80 foot tower, unguyed, and just resting on the concrete pad. Push it over so it pivot
I go to my local roofer/sheet metal guy. They always have scrapes left over from copper flashing, gutters, etc. you may have to pick and choose but the price is usually VERY right. Weather Stations",
On Discovery channel, they showed Lighting research and shooting rockets trailing a thin copper wire with a Kevlar core into storm clouds. The resulting lightning bolt did vaporize the wire. But do y
I did this also a while ago. There is no way you can do this without taking the tower apart. It MUST be down, horizontal, and you have to remove the top section to replace the lower cable connection.
sorry, and I don't have the drawing or remember the sizes. but it's pretty simple O== 5/16" 1 end with loop , other end with none then other cable exactly the same call them on the phone, I know they
George Good points. I have a slightly quicker and easier way of stabilizing the antenna while removing the rotator. I have an old boom to mast mounting plate on the mast, above the bearing but still
As an retired Chicago Licensed contractor I give my suggestions. The situation with siding, either aluminum or vinyl is the possibility of bending or cracking. So with suggestions geared toward avoid
a plumb bob, using 'piano' wire will support a VERY substantial weight and hang fairly still. This is how we installed elevator rails. But: The last few times I did towers, I went to my friendly RENT
I used a transit for years. I switched to the laser because you don't have to be looking through the glass while adjusting. Line the laser up and you can turn the base adjusting nuts and watch the re

By Passive I mean ducted central air. With the air system remotely located to insure quiet. I get just a touch of 'rushing' of the insulated duct work that is made of that flexible insulated round si
I have the older Wilson Rotating tubular type tower. I used a thrust bearing on the mast which extends out of the Wilson tower, with a length of square tube bolted to the bearing's mounting plate. Th
Bribe someone to do it for me. OK, devil made me say that. My favorite tower tip is when painting tower rust spots, start at top and work down. -- Stop the Slaughter! Boycott Baby Oil! -- W9OL, Bill
