Superior Noise Immunity Featuring reduced sidelobes and backlobes, the airMAX®ac Sector Antennas are engineered to reject noise interference in co‑location deployments. Market-Leading Beam Performance Compare the diagram of the airMAX®ac Sector Antenna, model AM-5AC22-45, to the diagram of a standard sector antenna, and note the superior noise immunity and beam performance of the AM-5AC22-45. Industrial-Strength Construction airMAX®ac Antennas are designed with robust mechanical design for outdoor application use. Plug and Play Integration Every airMAX®ac Antenna has a built-in Rocket™mount, so no tools are needed to install the Rocket BaseStation.
