COMPACtenna Model 2M/440 Dual-Band NMO Mobile Antennas

COMPACtenna Model 2M/440 Dual-Band NMO Mobile Antennas are very small, high performance dual-band antennas. Even though they're only 7.5 inches tall, they provide superior Omni-directional coverage far beyond their size, using a unique, patented* Electric-Magnetic Field Diversity design. These are attractive, rugged and weatherproof radome style mobile antennas that will allow vehicle passage into most garages, drive-through lanes and even under low tree branches without having to remove or tilt the antenna structure.

COMPACtenna NMO Mobiles are easy to install and use, requiring no tuning. This dual-band model covers the two most popular VHF and UHF amateur bands, 2 meters and 70 centimeters. A typical SWR under 2:1 across the frequency ranges 144-148 MHz and 420-450MHz, depending only upon the vehicle mount or base mount position. This antenna handles up to 85W on the 2M band and 50W on 70 cm. Its industry standard NMO base is compatible with a number of NMO vehicle magnet mounts, grounded NMO hole-mounts, hatch or trunk lip mounts or angle bracket mounts. The required NMO mount is not included with the antenna, but is available from DX Engineering.

The revolutionary COMPACtenna Model 2M/440 Dual-Band NMO Mobile Antenna is also configurable as an indoor base or as an inconspicuous outdoor base antenna by adding an optional CompacCounterpoise. It may be mounted in an attic or other stealth location.
