POLE SPECIFICATIONS:
2" SCH 40 2 " O.D. x .154 Wall x 72" Long Steel - CM PN 611652931 w/Oval End and
Powder Paint Finish.
1. When wind velocity exceeds 108 MPH on the 90cm antenna at heights shown, the
ground pole must be a heavy wall pipe as follows: 2" pipe (2 " O.D.) Schedule 80
(.218" wall thickness) and purchased locally. Field weld
Fig. 1.0 to prevent rotation in the concrete or use 3" O.D. ground pole and AZ/EL cap.
2. These charted values based on using Model 611652931 ground pole, 2.375 O.D. x
1.54 wall. When wind velocity exceeds 108 MPH, use 3" O.D. ground pole and AZ/EL
cap.
3. Pole and foundation design based on the following criteria: (a) Uniform Building
Code Exposure C and 1.5 stability factor, (b) Vertical soil pressure of 2000 pounds
per square foot, (c) Lateral soil pressure of 400 pounds per square foot, (d) Concrete
compressive strength of 2500 pounds per square inc h in 28 days.
4. CAUTION - The foundation design shown does not represent an appropriate design
for any specific locality since soil conditions vary and may not meet design criteria
given in Note 1. You should consult a local professional engineer to determine your
soil conditions and appropriate foundation.
