3” O.D. x .148 Wall x 72” Long Steel w/Powder Paint Finish - CM PN 611685101.
1. 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 inch in 28 days.
2. If Model 6851 (3” x 72”) is used for 90cm and 1.0m Antenna Dimension “B” on pier foundation must be increased by 4” and concrete
volume will increase accordingly.
3. 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.
