Tower Guy Wire Setup ?s

[vdubb16]

The project in hand is a used Rohn 20G tower, Tilt base, 60ft of tower. Supported at roofline of garage at 10ft. to a 4x6 16 ft pole cemented 4 ft down standing vertical at the back of the baseplate.

Ive been browsing the web for what all components are needed.

Please feel free to provide links to any items required so i know exactly what your talking about. If you know where to find the best deal, and dont mind sharing. id greatly appreciate it.

1. First off, for all intensive purposes normally the bigger the better. But honestly what is the load rating for 20ga 6 strand guy wire? It would be nicely inexpensive but i cant believe that this would suffice for my purpose... i could be wrong tho.

"further reading" Rohn says to use 3/16 guy cable which is somewhere between 4-5 guage i think. So i doubt 20 ga will do. or the turnbuckle i listed"

2. This is the most ideal solution for attaching to the tower. "again an assumption." But kind of pricey.

Will something along these lines work instead at a fraction of the price? One on each corner of the tower?

3. Any other options for the ground end of the guy aside from digging holes pouring cement with a rod of some sort. Again likely the most reliable method. just looking for any cheaper or easier alternative and ideas in general. Ground conditions are roughly 3-4ft deep sandy dirt then more dense soil there on down.

How tight should the guys actually be. If the above guy wire will do the job i assume these turnbuckles will work aswell. Turnbuckles with alil more length of adjustment might be better id think. depending on how much slack can be pulled tight by hand. again 20 gauge id expect that to be easy.

If i remember correctly at 60 ft rohn's pdf stated the guys to be at a 41 or 42 degree angle. Since its supported at 10ft high already, should i still guy at 30ft or go up to say 40 or so ft. and only need one set of guy wires x3. and go to the ground. quick mind math appx guy lenth of 60 ft. alil extra wont hurt. that is guying at 30ft high on the tower.

more to come ill add as it comes to mind. Please chime in, welcome any constructive cirticism. I dont want to skimp on whats needed. but tring to work bargins here.

as i still continue to read, i think ive answered some of my questions, but any input is welcome.

and im still unsure of what the anchor point of the guy wires into the ground should be. a long threaded steel bar with a bend at the bottem buried in concrete? and find some way to attach the guy to that?

also i was misunderstanding rohns pdf. with the angle and such. that was irrelevent. it gave the length of th cable. the distance up the tower, and the distance from the base to be mounted.

60ft tower
guyed 28ft high
with a cable 56ft long
48ft away from the base

and...
guyed at 55ft
with a cable 55ft long
48ft from the base.

Your second post is fairly close. Guy close to the top of the tower and then a set distance out from the base. That will assure the proper angle and force applied to the system.

As for the guy anchors, I have 6 feet of 2 inch steel pipe driven into the ground with the top 3 feet encased in concrete with a steel rebar cage around it. Extremely easy to do and very cheap. I think I have $40 into my guy anchors.

What I would caution you about is the use of Rohn 20. It is an EXTREMELY light duty tower. It looks like Rohn 25, but has vastly different strength capabilities. At 60 feet, it is going to need serious support. 20go guy wires will not do the trick. 3/16 cable would be better. Especially in your area. If you were to take a hurricane strike, you need all you can get.

I have about 60 feet of Rohn 45 up in the air. It is about 4X the capability of the 20. Mine is set into a huge concrete base, bolted to the house at almost 20 feet, and guyed near the top with huge cables. It is built to exceed Rohn's 110mph wind ratings (we get a LOT of wind here). Now, I do have some monster HF yagis up there, but it is worth considering where you are comfortable.

Because of the nature of radio work, the day WILL come when you need to climb your tower ( I have to at least once per month). You need to make sure it is capable of supporting you.

But with the tilt base from the OP's spec, I'd be very careful to lock that base down well prior to climbing. It may hurt a bit if it came loose and tilted over while you were up at the 60' level.
