It's intuitively obvious (as my engineering professors used to say) that adding very-slightly _slack_ guys to a self-supporting tower can do no harm, and that when the wind blows they will help. They
I keep a set of guys at around the 56 foot level of my old 64 foot Heights aluminum tower which is supposed to be self-supporting for around 15 square feet. Although the windload is around 9 square f
I have a 70' Universal aluminum freestanding tower that I also felt uncomfortable climbing. I installed guys at 35 and 70 feet to minimize the movement. Most of the sections are 26" and it seems logi
Yes - these things are like wet noodles in the air. Shudder. Well, not all logical things are correct. And based on earlier posts, your supposition isn't correct. Cheers, Steve K7LXC TOWER TECH - Pro
Steve, My Universal towers [properly installed] have never been uncomfortable to climb, nor have they ever swayed while being climbed. As for adding 'emergency guys', I've never done it, but do agree
This subject sure has brought a lot out of the wood work. Too many areas, all grey, ie, all explanations appears to have many variables and no real conclusion can be drawn from the thread. Now that t
Wow, that is one strong tower! <snip> I have an 80 foot Trylon. Even if I swing my 250 pounds back and forth at the top, I can't get it to sway even a 1/4 inch. It is significantly RIGID. <snip>
1. I agree with Yuri and Chris (and, IIRC, Bud Hippisley, K2KIR) on this basic technical issue. 2. I said as much in a brief post of my own before either had posted their comments. However, this is n
You might want to take a look at K7NV's web site for his Yagistress software. Kurt has published a very interesting study there of guyed tower mechanics, using finite element analysis software to ass
IMO, good post, Chuck--thanks. I know that I am continuing to learn from this discussion; keep it up! (Real-world experience or not, _I_ am impressed with your credentials!) 73 es gl Jim, W3WV [snip]
There is an example for self-supporting tower being guyed, which probably means if you plan on going over the specified top load guying would be the thing to do. Here in Canada a company back east ca
OK, guys. As the instigator of this thread (which has been interesting, to say the least) I'd like to provide an opportunity to review my original post, submitted as a challenge (tongue-in-cheek) to
Chuck, Have a look at: http://www.c-conceptsinc.com/index.html C-Concepts has excellent page, slide presentation, engineering software that can be used for 30 days (cost over $5k), bunch of examples
