Driving home today after a recent thunderstorm, I saw a crank up (telescoping triangular tower) BROKEN completely in two pieces with the beam hanging nearly on the ground. This was a fairly heavy dut

Though I agree with the intent of the comments, which I think was "too many guys overload their towers or don't install them correctly", I think that it is quite incorrect to categorize all self-supp

I just came from looking at the specs for the AN Wireless self-supporting towers (www.anwireless.com). I had been thinking of a 60' tower to support my 3-el SteppIR (by no means large: less than 7 sq

If you have ever had a tower come crashing down, you would know that it is much better to do the "right" thing up front than have a big mess sitting in your back yard. 73 Bernard, WA4OEJ beam only ge

Trylon makes one of the better self supporting crank up towers and is probably the one I would buy. That said, a Trylon T600 64 foot tower with 1/2 inch radial ice with 100 mph winds is rated for 0.0

Perhaps I wasn't clear: a 50' AN Wireless Light Duty tower *will* handle the SteppIR in a 100mph wind. To put the antenna that extra 10' higher would necessitate going for the Heavy Duty model costin

I'm not sure when Trylon started making crank-ups. As far as I know, they never have. They make self-supporting free-standing towers, as well as guyed commercials towers, but not crankups. Can they f

It seems to me that the issue here is not the design of towers or the ratings of same: it's of operator error in poorly planning the construction of his crank-up tower and then leaving it up during c

Another thing: as I understand it, the tower manufacturers' permitted surface area figures assume that the antenna is mounted immediately at the top of the tower. When that same antenna is mounted 5,

From correspondence with AN Wireless I learned that they claim their permissible load/area figures are still good for an antenna mounted within 10' of the top of the tower. Alan AB2OS I wrote: Anothe
