Soil borings and foundation analysis should be performed by a qualified civil engineer. A typical foundation design based on normal soil condi- tions is shown Figure 2. This design represents the mini- mum requirements for the foundation, and defines the interface requirements between the antenna and mount. A copy of this design is available from ASC Signal on request. Refer to Drawing 303544. 2' [609.90] TYP Anchor Bolt Requirements A typical anchor bolt installation configuration and corre- sponding dimensions are shown•in Figure 3. ASC Signal Type 303546 Foundation Kit includes, anchor bolts, and required mounting as shown in Foundation Orientation Proper foundation orientation is required to obtain the desired orbital arc coverage from a particular site location. The required azimuth and elevation angles of the antenna, relative to the mount, must be determined to establish the appropriate, foundation orientation. 18'-6' [Bs36.80] U BURNOY #CAR6426 CABLE TO ROD 9•-3' [29I9.40] TYP —� CONNECTORS. ]/4 [19] DIA Y.
