Ruijie Reyee RG-ANT20S-90 is a 2×2 MIMO outdoor sector/support antenna designed for point-to-multi-point (PTMP) base-station use with Ruijie AirMetro radios. With a high 20 dBi gain and narrow elevation beam, it extends link range and sector coverage for WISP, CCTV backhaul and campus deployments.

• 20 dBi peak gain (5 GHz) with 90° horizontal × 7° vertical beamwidth — ideal for sectorised base stations.
• Operates across 5.150–5.350 GHz, 5.470–5.725 GHz and 5.725–5.850 GHz (country restrictions apply).
• IP55 weatherproof enclosure; rated for harsh outdoor conditions and high wind survivability (~220 km/h).
• Includes mounting brackets and RF cable(s) in the package; designed to pair with Ruijie AirMetro base stations and managed via Ruijie cloud / Reyee tools.
• Surge/ESD protection specified for compatible systems (surge 6 kV; ESD ±24 kV).

Use cases: WISP base stations, PTMP bridges, long-range backhaul and outdoor campus networks. Installation: follow the supplied installation guide; ensure correct alignment, grounding and local regulatory compliance for 5 GHz operation. For safety and warranty coverage, consider professional installation for tower or rooftop mounts.

Regulatory note: Frequency bands may be restricted by country — confirm local licences and CE/UKCA requirements with your supplier before deployment.
