[TowerTalk] Measuring Guy Positions

[Mark Robinson]

I have my new 100 foot Rohn 45 set to go up on the gable end of the house. I 
have a wall bracket at 18 feet tied into the second storey ceiling joists. I 
can remove this wall bracket later if it proves to give me problems and yes 
I will probably never do a wall bracket again.

I have set the rear guy back 108 feet at right angles to the gable end of 
the house. Using string to layout right angle triangles and a triangle with 
30 and 60 degrees and a hypotenuse of 97 feet, I have marked the postions of 
the other 2 guys set 120 degrees from the rear guy line. Since the guys 
stradle the house and I have trees and a pump house I cannot see any guy 
anchor postion from any of the other guy anchor location . When I get the 
tower up to 30 or 40 feet then I will be able to see all three guy anchor 
points from the tower vantage point. I would like to check the 120 degree 
spacing of the guys at that time before digging any anchor holes. What is 
the easiest way to measure the angle between the 3 marked guy anchor 
postions from my vantage point on the tower.
