Chapter 1 - General Information
[10.2 cm] diameter with at least a 36 inch [91.5 cm] bend radius. Refer to the
individual foundation sections of the manual for specific recommendations
of conduit placement.
1.3.6 Loads and Deflections
The pointing accuracy of the installed antenna is determined by the stiffness
of the antenna and the foundation. The suggested foundation plan for each
mount type has been designed using the stated assumptions with loading
based on the corresponding loads table. The foundation should be designed
for a maximum tilt of 0.1 degrees when the survival wind loads are applied
to the antenna.
1.3.7 Soil Bearing
The minimum safe soil bearing capacity for monolithic foundations shall be
not less than 2,000 lb. per sq. foot [96 kPa], The bottom of the foundation pad
must extend below the frost line.
1.3.8 Anchor Bolts and Template
Anchor bolt locations must be within 1/16 inch [.16 mm] of the dimensions
given. The anchor bolt template kit includes the plates and tie bars necessary
to accurately position all of the anchor bolts for the foundation. The surface
of the concrete foundation at the mount base plates should be level within
0.5 inch [1,2 cm].
1.3.9 Reinforcing Bars
Reinforcing bars shall conform to ASTM A615 grade 60. Do not weld anchor
bolts to reinforcing bars. This will remove the temper and reduce the strength
of the anchor bolts.
1.3.10 Concrete Strength
All concrete shall be building code standard weight 3000 lb. per sq. inch
[20685 kPa] compressive strength at 28 days.
