IMPORTANT NOTICE

VIASAT DOES NOT REPRESENT, NOR RECOMMEND THAT ANY

PARTICULAR DESIGN OR SIZE OF FOUNDATION OR STUD IS

APPROPRIATE FOR ANY PARTICULAR LOCATION OR INSTALLATION.

SINCE SOIL AND ENVIRONMENTAL CONDITIONS, BUILDING CODES,

INSTALLATION PRACTICES, AND OTHER FACTORS VARY AMONG

DIFFERENT LOCALITIES, THOSE PERSONS INSTALLING ANTENNA

MOUNTS ARE CAUTIONED TO SECURE PROFESSIONAL

ENGINEERING SERVICES FOR THE DESIGN AND CONSTRUCTION

SUPERVISION OF ANTENNA MOUNT FOUNDATION.

INTERPRET DIMENSIONING AND TOLERANCES PER ASME Y14.5-2018.

ALL FOUNDATION CONSTRUCTION AND DETAILS SHALL BE PER LOCAL

CODES AND REGULATIONS. SLAB SHOWN IS FOR REFERENCE ONLY. SLAB

SIZE AND SHAPE SHALL BE DETERMINED BY CONTRACTOR TO MEET

FOUNDATION LOADING REQUIREMENTS LISTED IN THE FOUNDATION

LOADING TABLE ON THIS SHEET. SEISMIC LOADING IS NOT CONSIDERED

SIMULTANEOUS WITH WIND AND ACCELERATION LOADING.

USE PROVIDED VIASAT ANCHOR BOLT TEMPLATES TO ESTABLISH ANCHOR

BOLT SPACING DURING FOUNDATION CONSTRUCTION. THE TEMPLATES

AND STUD SUBASSEMBLY SHOWN ON SHEET 2 SHOULD BE SUPPORTED

BY A RIGID STRUCTURE TO MAINTAIN ANCHOR STUD VERTICALITY.

ANCHOR BOLTS SHALL NOT BE WELDED.

MAXIMUM FOUNDATION COMPLIANCE IS LISTED IN THE LOADING TABLE.

COMPLIANCE IS ANALYZED ACROSS THE BOLT PATTERN ONLY WITH

LOADING APPLIED TO THE BOLTS. THE FOUNDATION UNDER ALL LOADS

MUST BE STABLE IN ALL SEASONS INCLUDING FROST LINE, MOISTURE,

AND OTHER SOIL CONDITIONS.

SURFACE OF CONCRETE PAD INSIDE OF DESIGNATED AREA SHALL BE

LEVEL WITHIN 0.25 INCH. OUTSIDE OF DESIGNATED AREA SHALL BE

DESIGNED FOR PROPER DRAINAGE AWAY FROM THE ANTENNA. STUDS

AND AREA AROUND STUDS SHALL BE FREE OF CONCRETE BUILD UP. IF

GROUT IS REQUIRED, THE PAD SURFACE AROUND THE BOLT PATTERN

SHALL BE LEFT ROUGH FOR GOOD GROUT BOND.

NOTES:

MOUNTING STUDS ARE PROVIDED FOR CONVIENENCE. STUD LENGTH TO

BE DETERMINED BY CONTRACTOR PER FOUNDATION ANALYSIS. IT IS

CRITICAL TO ANALYZE THE STUDS AS PART OF THE DESIGN TO ASSURE

LENGTH PROVIDED IS ADEQUATE FOR THE SITE. SEE DETAIL ON SHEET 2

FOR DIMENSIONS OF THE HARDWARE PROVIDED. ANTENNA MOUNTED

DIRECTLY ON TOP OF THE FOUNDATION.

COMPLIANCE IS DEFINED AS THE RATIO OF THE AMOUNT OF TILT OF THE

FOUNDATION, ϴ, TO THE OVERTURNING MOMENT THAT IS APPLIED TO IT.

EXPRESSED IN RAD/FT-LB.

THE RADOME RING WALL, IF INCLUDED, SHALL BE ISOLATED FROM THE

PEDESTAL FOUNDATION SUCH THAT WIND AND TEMPERATURE LOADS ON

THE RADOME ARE NOT IMPARTED ON THE PEDESTAL FOUNDATION.

FOUNDATION COMPLIANCE APPLIES ONLY TO PEDESTAL FOUNDATION

PAD.
