Hi, I am fairly new to towers and I have tried to research information on rohn's 25, 45 and 55 towers. I have found quite a bit of information on these towers but not the exact answers that I am look
Many of the towers made today are designed to sway and you dont want to guy them such as the popular line of Universal Aluminum towers. The steel towers are built to be self supporting to a certain h
I may be completely off base with this, and if I am, I'll apologize right now. With the Rohn BX, and HDBX series of towers, the "square foot" changes according to model. But I swear, I thought I read
5.5 square feet? Do you mean CUBIC feet? If so, that is definitely NOT enough concrete. 5.5 Cubic YARDS makes more sense to me, as my Universal towers ALL have from 4 to 6 Cubic YARDS of concrete bel
Mike: You're correct - the BX-series of antennas has a torque limit on them. This is because they are assembled with rivets, not welds, between the cross pieces and between the cross pieces and the l
I will confirm what Gene is saying about the BX towers who's cross members are riveted, not welded. In my youthful radio career, I put up 104 ft of HDBX tower. It was 4-way guyed at several levels. I
Bob: Which model Trylon tower is riveted? I own a T-500-64 (Trylon's Titan design) and I built the thing myself with SS bolts and associated HW. I didn't want readers to think that ALL Trylons were r
C'mon fellas - none of you answered this guy's question but instead hijacked the thread and started on about other things not even related to his question... Steve, my understanding is that the maxim
Folks: Been there, done that, on a Rohn 25, 50 footer free standing, of a ham friend, donating some tower work....The tower was professionally installed, with what looked like a 5' by 5' square concr
Gene, This might be a case of acute C.R.S. of my earlier radio career...! I worked on 2 different Trylons. These were both delivered as nestled, "assembled" sections, not as put-together kits. But no

Oops. Meant this to go to the reflector. _______________ As I recall, Rohn said you could have up to 33 feet of unguyed tower above a housebracket. I have never seen anything about unguyed without th

I am only quoting figures. I am not making any recommdations. According to the ROHN catalog I have in front of me. Self supporting 2.3 safety factor 70 MPH, 34.1' *Recommended* So ROHN recommends no
on these towers as well. Umm, I don't know what Trylon you looked at but they all use nut and bolts. In fact most of the nuts have little imbedded star washers on them which makes them real easy to u
I have owned a Trylon in which most of the upper sections used rivets. This is not the norm, though. I believe it was quite an early model - or someone choose to use rivets - as I would agree that cu
I've been following this thread and most of the answers you got were either flat wrong or based on some anecdotal info that clearly exceeds the manufacturer's specs. And the examples you cited above
