Astro Omni-directional Antenna 4-40GHz (AOA440)

The AOA440 by AstroAntenna® is an industrial/military strength Omnidirectional RV, vehicle, mobile, railway, truck, train, boat antenna and can be used as a reference test antenna in the laboratory. The antenna is highly suited for modern and upcoming 5Gs and can be ideally used in multiple applications like mobile communication, countermeasures, monitoring, jamming and military applications. The AOA440 is made with thick fibreglass and military-grade aluminium to withstand even the harshest of environments.



The AOA440 is providing maximum propagation omnidirectionally on all frequencies between 4GHz and 40GHz. The AOA440 can be used with a variety of radio equipment systems, including single-connector modems, hotspots, and routers, and with boosters, amplifiers, and repeaters (as the external antenna). The AOA440 is fully enclosed and all-weather resistant and requires pole mounting, where the pole can be either vertical or horizontal. The connector on the AOA440 is K Type female. The AOA440 is made in the United Kingdom with domestic and imported components and includes a one-year warranty period. Patent pending.
