[TowerTalk] Rohn 25 Guying

[Stan Stockton]

I have 70 feet of 45G at my current QTH.  It has been guyed to the same two oak trees for over 40 years.  There is either 3/8 or 1/2 inch wire rope around the trees through old garden hose with wire and rope clamps holding those loops together.  Turnbuckles attach to the loops which are a few feet out from the trunks.  The other guy anchor is more traditional.  I have more worry about the more traditional one that is over 40 years old than the trees which are probably older than I am.

The tower is guyed at 30 ft, 60 ft, 90 ft, and 120 ft with carefully tension 3/16" EHS (except that the top guys are Phillystran for the first 30 ft or so from the tower). Each wire is attached to a 6-in x 1/2-in lag into a different tree within 3-4 ft (that is, 9 different trees). The lags enter the trees at an upward angle of about 30 degrees.
