My 1960s Rohn catalog shows the upper guys usually connected to the top of
their towers. Current Rohn literature shows it down about 5 feet from the top.
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.
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.
