Don't know what book says. Been under impression for 40 years or more they
were free standing (25G) up to 60 feet especially with a house bracket. I
put one up at 55 ft in 1981, self supported with tri-bander, it is still
here! and we have had several really high wind attacks, a nasty ice storm..
My book says no more than 60 feet without guys while constructing. The 135
footer I put up in 1965 had guys 60, 90, 120 feet.. it is still there! Don't
know.. go figure! Mike K4XM
