I have installed over 85 Rohn 25G towers in the past 30 years. Many have
been 40-50 foot with the proper base and no guy wires. These have been for the
CB'ers and Ham radio operators. These also have anywhere between 3 & 6 element
beams. Never have heard of a problem with any of these. I know of a 70 foot
Rohn 25G tower that has a 4 element Moonraker beam with no guy wires. It has
a 5'x5'x5' concrete base and still standing after 25 years of North Louisiana
weather....W5KGT

Uh, Kevin installed my tower out here in KH6. Kevin has a pretty big brass
set to hover above the ground on 50 feet of unguyed Rohn 25...especially with
a tribander on top. This is an accident waiting to happen.
In Florida I saw the results of what a hurricane can do to Rohn 25 and it
ain't pretty. With several hundred pounds of tower and antenna at that
height,
the installation can be lethal.
Just because you can do something doesn't mean it's safe. I can drive with
without using my hands for a while and just because I can do it doesn't mean
it is a smart thing to do.
YMMV.
