Not a bad idea. With a short top section, there is plenty of room. We actually assembled the top section, rotor plate and the final 10 foot section of tower on the ground before hoisting it up. Made

How big is your top section? My 3 foot tapered section has plenty of adequate space at the bottom where it and the section below it meet. I wouldn't lie about that and I can prove it with pictures. S

I just looked at the Rohn catalog sheet. The 25AG4 top section is 8' 3/16" long. The spot for the rotor is 1' 4" 3/4"(or 16 3/4") from the top. That's plenty of room to mount the rotor plate and roto

The tower was (and is) guyed at 25 feet (so noted on the page). So, in reality, they were less than 30 feet above the first set of guys. Clearly w/in specs. I had to un-guy the tower and correct the

Hi Bill, What's your call sign? As a relative newbie to towers myself, a lot of the questions and answers are still in my mind. 1.) What are you planning on using the tower for? Thirty-five feet isn'

I'll agree that grounding on a roof tower is much more difficult and structurally, there's some work that must be paid attention too. But that structural work is not any more difficult than building

Hi gang, What's the difference between a Ham IV and a Ham M? I thought that the Ham M didn't have the wedge brake assembly and so was a little shorter but otherwise they were the same. I just bought

I did some reading and one of the major differences appears to be that the Ham IV uses a stainless steel ring gear as opposed to the pot metal gear. The rotor I bought was just rebuilt with the stain

Thanks all for all the info on the Ham M vs. Ham IV rotors. Here's one final question: I need my new Ham M to rotate through South as it's going to be an azimuth rotor for my satellite station. Where

I've heard about this. But I think the ISA slot is only used for supplying power from what I have read so you can externally power the card. The problem (from what I remember) is that the Sartek mode

I'd agree with that. It may also depend on how they define the terms. Every antenna has a figure for "radiation" resistance. Could they be basing it on that? Or is it the power lost in the loaded coi
