FIG. 4.1 - ANTENNA, ANTENNA FEED (LNB) & FEED SUPPORT LEGS
POLE SPECIFICATIONS:
2” SCH 40 2³⁄₈” 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 (2³⁄₈” O.D.) Schedule 80 (.218” wall thickness) and purchased locally. Field weld ¹⁄₄ x 1¹⁄₂ x 5 key as shown in 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.
