Slippage can cause the corresponding assembly to move, causing antenna misalignment. When designated, the A-325 hardware should be tightened according to the following tensioning procedure. NOTE: Tensioned bolts are for final connections only and should not be loosened for reuse. Lubricate the bolt threads with the provided stick wax to reduce friction. Insert the bolt, and add a flat washer—if required. Do not allow wax under the flat washer. Add the nut, and finger tighten. After the connections are complete, tighten the bolts until the surfaces are joined and the nuts are snug (for example, full effort of a person using an ordinary spud wrench). Do not proceed with Steps 5 and 6, unless the connection is final and is not intended to be loosened again. Note: If the bolts are loosened after Steps 5 and 6, discard and replace with new hardware. Using a felt-tip marker, mark the nuts and the ends of the bolts with a straight line as shown in Figure 3-1a and Figure 3-1b. Tighten the nuts further with an extra long wrench until the nuts are moved 1/3 turn (120 degrees) as shown in Figure 3-1a for bolt lengths less than four diameters and 1/2 turn (180 degrees) as shown in Figure 3-1b for bolt lengths over four diameters.

The mount enables continuous elevation adjustment from 5 to 90°. Azimuth adjustment is ±90° and divided into three 120° ranges with 30° overlap. Follow the subsequent procedures for proper installation of tripod ground mount assembly. All ground mount hardware is type A-325. Lubricate all A325 bolt threads with supplied stick wax. Note: Do not tighten hardware until ground mount installation is complete unless otherwise instructed. Attach 200056 and 200057 supports to upper portion of 201408 beam assembly as shown in Figure 3. • Use 7/8 x 2-1/4 in (57 mm) hardware Figure 3 Raise 201408 azimuth beam assembly and attach to front foundation pad as shown in Figure 4. • Use 7/8 in. flatwashers and hex nuts Note: Hex nuts and flatwashers supplied with 201630 anchor bolt kit Figure 4 12 Installation Procedures Support LegsAssembly Step 1 Step 2 Attach 201327A joint assembly to 201313A beam assembly as shown in Figure 5. Attach 200083 angles to 201313A beam assembly as shown in Figure 5. • Use 7/8 x 2-1/4 in (57 mm) bolts and nuts for each connection Figure 5 Attach 200088A joint assembly to 201313A beam assembly as shown in Figure 6. • Use 7/8 x 2-1/4 in (57 mm) bolts and nuts Figure 6 13 Installation Procedures Raise 201313A beam assembly to upright position and attach 201315 supports to 201327A joint assembly as shown in Figure 7. Step 3 • Use 7/8 x 2-1/4 in (57 mm) bolts and nuts • Insert bolts from 201327A joint assembly to supports • Supports should be installed back-to-back with the flat of angle facing upwards • Tighten supports until assembly can support itself Step 4 201315 Supports Figure 7 Attach 201301/201302 rear pad assembly to 201315 supports as shown in Figures 8 thru 10. • Use 7/8 x 2-1/4 in (57 mm) bolts and nuts • Insert bolt from inside of rear pad assembly to outside of support • Supports should be installed back-to-back with the edges forward and the flats of angles facing rear Figure 8 14 Installation Procedures Attach 201314 supports to 201301/201302 rear pad assemblies and 201273 joint assembly as shown in Figures 9 and 10. Step 5 • Use 7/8 x 2-1/4 in (57 mm) bolts and nuts • Insert bolt from inside of joint assembly to outside of support • Supports should be installed back-to-back with the edges forward and the flats of angles facing rear Step 6 Figure 9 Attach 201317 supports between angle pairs as shown in Figure 10. Select corresponding mounting holes so that 201317 supports are parallel to 201313A beam assembly. • Use 7/8 x 2-3/4 in (70 mm) hardware • Supports attached with edges inward and flats facing up.
