Default Rohn 25G without guys, how high?

sorry, think again... no hinge bases allowed on free standing towers. those
are only for guyed or bracketed towers. free standing towers must embed the
base section in concrete.

Wow. You're a better man than I am, Gunga Din. :-)

I actually wasn't planning on climbing it, rather planned on using one of
their hinge-over bases to raise and lower it when needed. I was thinking
of 40 feet, max.

To answer J's question... it's in a suburban setting on 2 acres of land,
and where the tower will be, if it fell over it would be all on my
property (i.e. no danger to neighbors or passersby). We're sufficiently
protected by trees such that only once in the 22 years I have lived here
have I seen winds of over about 40 MPH at below-the-treetops level (around
60-70 feet).

I have another Rohn 25G tower on the other end of the house that is
currently 40 feet, and I am in the process of adding another 10 feet for a
total of 50. It is guyed at the 30-foot level. I had to remove the top
section to add another 10-foot mid section, and now I'm in the process of
rasslin' the top section back into place (oh, so much fun). So, that'll
be 20 feet unguyed on top of 30 feet guyed. I'm trying to decide whether
I want to put a tribander on top of that or maybe get something light like
the Butternut Butterfly. I'm not a huge DX freak so don't really need a
full size multi-element 20-meter beam.
