The RF Elements Array Sector 5-20 in depth

What it is

The Array Sector 5-20 is RF Elements' conventional high-gain 5 GHz sector. It gives 20 dBi with about 80° (H) of azimuth coverage at −3 dB and a narrow 3.5° elevation beam, for long-range point-to-multipoint coverage.

BackShield

RF Elements built in its patented BackShield frequency-selective surface to attenuate azimuth side lobes and back radiation. The result is a 30 dB minimum front-to-back ratio, which matters when several sectors are clustered on one pole.

Radio mounting

The radio connects through two RP-SMA pigtails and mounts on the antenna. RF Elements lists fits for Ubiquiti Rocket and airFiber 5X radios, Cambium ePMP (with EasyBracket), MikroTik BaseBox/NetMetal, Mimosa A5x and RF Elements StationBox S.

Mounting and environment

It mounts on 40–80 mm poles (close to 80 mm recommended), is rated IP55 and 160 km/h wind survival, and weighs 3.5 kg.
