ROHN is very specific about the bolt insertion. They expect the assembler to use "Taper Pin" punches to enlarge the bolt holes to the point where the bolts will just fit. They do not want anything to

I use a vulcanized, nylon monofilament pole strap even on steel towers. It is extremely rugged, but also expensive. My pole strap has safety clips which require you grip *both* sides of the clamp an

In aircraft we "stop drill" by drilling a small hole at each end of the crack, but welding is not an option there. However we do the same with plexaglass windows. When drilling plexiglass though you

The ROHN catalog is very specific about not drilling galvanized tower legs. They don't even want the bolt holes drilled out. If the bolt doesn't fit they direct the builder to use "taper pin punches"

Yup. Brand new ROHN 45-G. That double hot dipped galvanizing fills holes, and leaves lots of little sharp things to poke holes in tender body parts. They tell you right in the manual about enlarging

That is not how a Metal Oxide Varistor (MOV) works. You *never* want one to open unless the rating is too low. They work by *shorting* transients. MOVs have two ratings. The first is of course the v
