30–512 MHzFeatures and BenefitsGround Plane AntennasDB201 series ground plane omni antennas feature a moisture resistant epoxy insulator to guardagainst condensation and corrosion in the 50 ohm feed-through connector. The lead is protectedwith a field replaceable, weatherproofed male-to-female connector. These antennas are constructedof all metal and all elements operate at dc ground to protect against damage from lightning. Theantennas are cut to frequency and factory tested for minimum VSWR. Optional uncut models areavailable with cutting charts.The ASP7A light duty quarter wave ground plane antenna, constructed of chrome-painted brassradiators and stainless steel radials, provides long lasting, dependable performance for all generalpurpose applications. This antenna easily mounts in minutes on a mast up to 1.25 in (31.8 mm) OD,and is an ideal choice for economical installations. DB201Exposed Dipole Quasi-Omni AntennasAndrew’s exposed dipole quasi-omni antennas feature flexibility for pattern shaping. By aligning theantenna dipoles collinearly, an offset pattern is produced offering a higher gain. Or, by positioning thedipoles evenly every 90° on opposite sides of the mast, a circular pattern is produced offering omnicoverage. Each model is designed with a center splice to assure proper alignment, and can easily befield adjusted with ordinary hand tools to produce the desired pattern performance.Additional Features DB222, DB224, DB228, and DB264 antennas perform efficiently in both transmit and receive,and most models are capable of operating in either single or multi-frequency systems.Dual dipole models (DB404, DB408, DB411, DB413, and DB420) are especially suitable forduplex operation. Each antenna is easy to install with optional side mounts available. Order DB5001 for sidemounting standard folded dipole antennas, and order DB5007 for dual folded dipole antennas. DB264 models are designed with the cable harness enclosed in the metal mast, and the mastand radiating elements are vented to prevent moisture accumulation. Dual folded dipoles are extremely rugged to resist winds up to 125 mph (201 km/h). Radiators operate at dc ground and each aluminum mast has a pointed cap that provides a lowresistance discharge path to the tower or ground system. DB22456Andrew Wireless Solutions www.andrew.com
