I just got through installing 80 feet of Rohn 45G. I have some 
good advice. Use Rohn specs on everything. The depth of the holes, 
the geometry of the holes, the distance from the tower base for the 
anchors, the number of guys and the proper size of guy wire. Use all 
Rohn hardware on the tower such as guy brackets, torque arms ect. Use 
only the very best EHS guy cable, insulators, preformed guy grips 
ect. The cure time on the concrete is very important. Here is a site 
that will help you determine the importance and technique for proper 
Look at the Rohn specs, get the re-bar in the ground and the concrete 
poured. You can be getting all your other " ducks in a row " while 
the concrete cures. 
Six men gave me a Saturday and we installed eight sections of 
tower, including one on the top,complete with two bearings, mast and 
rotor, using a gin pole, and three sets of guy wires. The heat was 
severe here in Alabama. We dropped a nice heavy plumb-bob through the 
center of the tower for alignment and torqued the guy wires. The plan 
was to use a tram line to raise the Mosely Pro 95 to the top. After 
weighing all options I decided to use a crane to set the antenna. 
Hind sight being what it is, I could have assembled the tower on the 
ground in two 40 foot sections and used the crane to stand them up, 
put the guy wires down, and raised the antenna in about 2-3 hours. Oh 
well, maybe this will help someone else to do it the easy and 
certainly the safest way. It has already survived an 80 MPH straight 
line wind and is rated for much more. I hope high wind don't come, 
but I have done everything by the book, cut no corners, using proven 
methods to install things here. 
By the way, the PRO-95 plays REAL NICE!
