FOUNDATION INSTALLATION (120° MOUNT)
____________________________________________________________________________________________
GENERAL NOTES:
1.
THE FOUNDATIION HEADING IS CRITICAL TO THE PERFORMANCE OF THE
MOTORIZED ANTENNA, BUT NOT TO THE PERFORMANCE OF THE NON-MOTORIZED
ANTENNA. THE FOUNDATION HEADING ESTABLISHES THE CENTER OF AZIMUTH
TRAVEL. FOR A NONMOTORIZED ANTENNA TO BE LATER UPGRADED TO
MOTORIZATION, THE FOUNDATION HEADING MUST BE INSTALLED INITIALLY
AS THOUGH FOR A MOTORIZED ANTENNA.
2.
PROPER ELECTRICAL GROUNDING SHALL BE PROVIDED BY THE INSTALLING
CONTRACTOR TO MEET LOCAL APPLICABLE CODES. DEPENDING ON LOCAL
SOIL CONDITIONS, THIS MAY TAKE THE FORM OF A BURIED GRID OR A
SUITABLE COPPER STAKE. THE ANTENNA MOUNT SHALL BE ELECTRICALLY
CONNECTED TO THE GROUND.
3.
PROVISIONS MUST BE MADE TO PROVIDE SUITABLE SUPPORT FOR POWER, RF
AND CONTROL CABLES EITHER BY BURIED CONDUIT OR OVERHEAD RACEWAY.
IF CONDUIT IS SUPPLIED, IT SHALL BE AT LEAST 3 INCHES DIAMETER.
4.
LIGHTNING ARRESTORS MUST BE PROVIDED ACROSS ALL CABLES LEAVING THE
ANTENNA PER APPLICABLE LOCAL CODES AND N.F.P.A. CODES.
5. REFER TO DRAWING 454595 FOR INFORMATION ON OUTLINE AND CLEARANCE
DIMENSIONS.
6.
USE NO NUTS UNDER THE FOOT, 454063. THE FOOT MUST REST FLUSH ON
THE CONCRETE PAD. USE ONE WASHER AND ONE FLOUROCARBONCOATED NUT,
337880, PER ANCHOR BOLT TO SECURE FOOT TO PAD. AFTER THE CONCRETE
IS FULLY CURED, TORQUE THE NUTS TO 245-270 FOOT-POUNDS.
FOUNDATION CONSTRUCTION NOTES:
1. THE MINIMUM SAFE SOIL-BEARING CAPACITY IS 2000 PSF.
2. REINFORCING BARS SHALL CONFORM TO ASTM A615, GRADE 60.
3. DO NOT WELD ANCHOR BOLTS TO REINFORCING BARS. THIS WILL REMOVE
THE TEMPER AND REDUCE THE STRENGTH OF THE-ANCHOR BOLTS.
4. ALL CONCRETE SHALL BE BUILDING CODE STANDARD WEIGHT 3000 P.S.I.
COMPRESSIVE STRENGTH AT 28 DAYS.
5. AREAS (6 X 12 INCH) FOR MOUNTING FEET SHOULD BE FLAT WITHIN 1/16
INCH AND LEVEL WITH RESPECT TO ONE ANOTHER WITHIN 1/4 INCH.
6. ANCHOR BOLTS ARE 1 INCH DIAMETER AND MUST CONFORM TO ASTM A193
