I should have mentioned this earlier.

One obvious advantage of this is that it give you a little more space when installing a big antenna, when you are trying to swing the elements from vertical to horizontal while clearing those guys.

In that case I'd much rather have the guys at the top than a ways down.  
They are easier to rotate around while also rotating the antenna, but as 
I said in the other answer I much prefer to use a tram line, but oft 
times there isn't room.

> Today I got the last section up for mine using Ginpole, top is at 45 feet. I installed a "Norms Fabrication" guy bracket up at 40 feet. That bracket isn't a perfect fit like the OEM bracket, but I think it'll do. Got one Phillystran guy up, but not tensioned, when a major storm front swept in. 30MPH gusts. A few hours ago I tried to climb up and fasten #2 and 3 guy to the bracket but the rockin and rollin of that 23 feet above the first guys convinced me otherwise. Expecting some snow later, and the wind is dying down now.
