Model: AM-5G20-90 (3-Pack) airMAX Sector Antenna 2x2 BaseStation The AM-5G20-90 AirMAX 5 GHz 2x2 MIMO Sector Antenna from Ubiquiti Networks provides networking flexibility and convenience by letting you create a customized base station with an optional RocketM radio. This antenna operates under the 5 GHz frequency and offers a gain of 20 dBi. The airMAX Sector Antenna is a Carrier Class 2x2 Dual Polarity MIMO Sector Antenna that was designed to seamlessly integrate with RocketM radios (RocketM sold separately). Pair the RocketM's radio with the airMAX Sector Antenna's reach to create a powerful basestation. This versatile combination gives network architects unparalleled flexibility and convenience. Reduced Interference, Higher Gain Highly resistant to noise interference, the airMAX Sector Antennas provide superior gain and beam performance for high-capacity, multipoint networks. RF Isolation and Beamwidth Options The versatile airMAX Titanium Sector models feature advanced RF isolation and adjustable beamwidth options: 60°, 90° or 120°. Industrial-Strength Construction airMAX Antennas are designed with robust mechanical design for outdoor application use. Plug and Play Integration Every airMAX Antenna has a built-in Rocket mount, so no tools are needed to install the Rocket BaseStation.
