The mount can be positioned manually or by using a crane; however, Andrew recommends that this procedure be performed using a crane to ensure speed and ease of installation. Figure 3-2: Crate Unpacking As stated previously, the pedestal ground mount installation process can be conducted manually or by using a crane. The following steps provide the necessary procedures for installing the ground mount assembly using a crane. 16 Installation Procedures Step 1 Step 2 Step 3 Step 4 Carefully remove t

• Use 7/8 by 2-1/4 in (57 mm) hardware Note: Angles are attached edge out with flat of angle facing inward. 301786 Figure 16 Align panning frame/azimuth pivot assembly by swinging panning frame through its entire arc. Slightly snug panning frame/pivot assembly hardware, and again swing panning frame through its entire arc. Continue this procedure until mounting hardware is ready for tensioning. Note: Do not tighten hardware on 301786/201022 azimuth pivot assemblies at this time. 21 Installation

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 connectio

The high-grade magnesium alloy material is lightweight, does not rust, and memorizes the antenna's parabolic curve to maintain its shape over time. The result is the only low cost terrestrial microwave antenna sufficiently durable to survive changing climate conditions. The patented grid reflector design provides field reliability and ease of handling and installation. No secondary coating is required to prevent rust and corrosion. Breakdown packaging saves freight costs, and optional factory a

When the dipole element pairs are spaced at 90° to each other, an omni-directional or circular pattern results. When both sets of dipoles are in line (collinear - see the DB404L illustration in Figure 1), the antenna has a directional characteristic, giving an elliptical pattern as shown in Figure 2. Also, see Figure 3 for gain variation with frequency for DB404 and DB404L antennas. The change from one radiation pattern to the other is easily accomplished. The banding clamps that hold the dipole

Be certain both feed rotation limit switch arms are not distorted and ride centrally on the actuating cam to open their corresponding limit switch. • Inspect the azimuth and elevation jackscrew boots for security of attachment at both ends, for abrasion, tears, cuts, brittleness and other damage that may expose the jackscrew to the environment (water, dust, etc.). Minor repairs can be made with RTV108 silicone rubber sealant. • Visually inspect the feed window for dirt and the feed, feed support
