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

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

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

Andrew installation instructions are written for such installation personnel. Antenna systems should be inspected once a year by qualified personnel to verify proper installation, maintenance, and condition of equipment. Andrew disclaims any liability or responsibility for the results of improper or unsafe installation practices. Do not install near power lines. Power lines, telephone lines, and guy wires look the same. Assume any wire or line can Do not install on a wet or windy day or when
