Nathan, I would caution you to not mix the sections nor even use the 20 for anything more than VERY light duty use. With that said... Back in my younger days when I did a lot of tower work for CB and
I also have experience with 20-G and 25-G towers... @ my station my 2mter/450 MHZ and one 6 meter beam 5 element 14' boom are on at 36ft. an consist of 3 sections of 20-G and a top of 25-G AG3 ? it's

Remember, 20G is only rated for 2 sq ft of wind load...IE a TV antenna. They, like many ham installations with other towers have supported much more than their ratings, but you are far past the rati
Wayne, I'll primarily be using it for wireless internet. Unfortunately, the tech at the WISP I spoke to was pretty vague about the wind load of the antenna they'll be using, but he assured me it woul
Roger, From what I've heard, Rohn discontinued 20G, I guess because nobody puts up TV antennas anymore. I guess I'll lean towards fixing some of the more questionable 25G sections I have. --Nathan Wh

Two levels of guy is what my concern would be. I am in as now and be home in PA next week. I have a library or Rohn catalogs and in the older ones I have the full spec on r 25 -G. But if my gray matt

25g is usable under Rev G 90mph up to 190ft with 5 levels of guys. Lightly loaded yes but usable. There are many 190ft AM broadcast and lightly loaded 2-way towers that have been standing for 30+ yea
My Bad :( I meant to say R-20-G ( Still on ESDT time and it was AZ time = 1:00PM to me ) 25-G is a horse of a different color ... _______________________________________________ _____________________
Steve The Dim for the two are the same except for the number of Z bars bays. and the fact of the OD of the Z rung material and the wall thickness of the vertical tubes , And yes this is Ham radio....
Here's the thing (well in my mind anyway). Just because Rohn's *vision* for 20G may have been 30', a house bracket and TV antenna, and for 25G it was guyed applications up to 190', doesn't mean that

20 was harder to climb even when I was 20 years younger and 50 lbs lighter. And a lot braver... Kevin C. Kidd, CSRE/AMD AM Ground Systems Company - WD4RAT kkidd@kkbc.com -- 866-22-RADIO -- 866-227-23
Is there a significant difference between guying and bracketing a tower? I'd expect them to behave about the same, but maybe house bracketing is more rigid since guys are springy. Alternatively, I he

There are too many variables to say for sure, but if you have ever been on the roof of a single story home, next to a large chimney, you will be amazed at how much the house roof and walls move. On a
In that case, I am not too worried about guying. I don't want to bracket the tower (I am renting so I'm putting the tower somewhere far away from buildings so it can't fall on them), but I will be bo
I can't seem to find any 20G pricing (which makes sense, as it isn't current production). I'm curious -- how much cheaper was 20G vs 25G? --Mike, WV2ZOW ______________________________________________

The last Rohn distributor price list showed 20G at the same price as 25G. 73, Gerald K5GW GM Texas Towers In a message dated 7/3/2014 10:41:35 A.M. Pacific Daylight Time, wv2zow@gmail.com writes: I c
