Detailed specifications and benefits

This section breaks down the RG-ANT20S-90s specifications and explains how each attribute translates into deployment benefits for real-world networks.

• Frequency range:Supports 5.150 65.350 GHz, 5.470 65.725 GHz and 5.725 65.850 GHz (observe local regulatory restrictions). This flexibility covers the common outdoor 5 GHz bands used for high-throughput PTMP links.
• Gain:20 dBi at 5 GHz. High gain focuses more RF energy in the sector, extending range and improving received signal strength for client radios. Higher gain also helps overcome environmental losses over longer links.
• Beamwidth:90 horizontal and 7 vertical. The wide horizontal coverage is ideal for typical sector deployments, while the very narrow vertical beam reduces interference between sectors stacked vertically and concentrates energy toward the coverage plane.
• MIMO / Polarisation:2×2 MIMO with dual / ±45 polarisation supports better multipath resilience and improved throughput to modern client radios.
• VSWR:≤ 2.0:1, indicating efficient RF matching and low reflected power across specified frequencies.
• Working distance:Rated for PTMP links up to ~10 km when used with compatible radios and favourable environmental conditions.

• Dimensions:Approximately 694 × 140 × 49 mm  a compact footprint for a sector antenna of this gain.
• Mounting:Includes mounting brackets and is pole-mount compatible for straightforward installation on masts, towers or rooftop rails.
• Weatherproofing:IP55-rated enclosure protects against dust ingress and sustained water jets, suitable for most outdoor installations (urban and rural). Note that IP55 is protective but not fully submersible; extreme marine or salt-spray environments may require additional consideration.
• Operating temperature:Usable in a wide temperature window from 640C to +80C, making it suitable for harsh climates.
• Wind survivability:Designed to withstand approximately 220 km/h (137 mph), offering robustness on exposed towers and poles.
• Surge & ESD:Surge protection to 6 kV and ESD tolerance ±24 kV are specified for compatibility with protective systems on supported radios; this improves system longevity where lightning and static discharges are a concern.

• Package contents:Antenna, mounting brackets, RF cable(s) and an installation guide are included, which accelerates deployment.
• Integration:Designed to be used with Ruijie AirMetro base stations and managed through Ruijie cloud / Reyee tools, smoothing provisioning, monitoring and scaling of multi-sector sites.
• Regulatory considerations:Frequency usage is subject to local regulation. Confirm licensing and CE/UKCA compliance with your supplier before deployment.

Use cases and scenarios where the RG-ANT20S-90 excels

The RG-ANT20S-90 is purpose-built for deployments where focused sector coverage, long range and reliable outdoor performance are important. Typical use cases include:

• WISP base stations:For wireless internet service providers building PTMP networks, the 90 sector angle provides broad horizontal coverage while 20 dBi gain extends reach to distant subscriber premises. The included mounts and cabling reduce installation time on tower sites.
• Campus networks:Universities, corporate campuses and industrial sites can use these antennas to create radial sectors from rooftop or tower locations, providing consistent coverage across walkways, courtyards and building clusters while minimising inter-sector interference thanks to the tight vertical beam.
• CCTV backhaul:High-gain sectors are useful for aggregating traffic from multiple outdoor cameras back to a central location, especially where fibre is impractical or cost-prohibitive.
• Municipal and smart-city networks:For municipalities deploying connectivity to public spaces, transit stops or sensor networks, the RG-ANT20S-90 provides reliable outdoor RF coverage with enough gain to reach remote nodes.
• Point-to-multi-point bridges:When a single base station must serve many fixed client nodes at varying distances, the 2×2 MIMO design and surge protection improve link stability and resilience under challenging conditions.

How it compares to similar market options

Understanding where the RG-ANT20S-90 sits among alternatives helps determine if its the right fit for your deployment.

Lower-gain, wider-angle sectors (for example, 12 6 dBi with 120+ beamwidths) provide broader horizontal coverage but sacrifice range and link budget. The RG-ANT20S-90s 20 dBi gain is a trade-off that narrows the vertical beam and preserves a 90 horizontal sector to reach further subscribers without dramatically increasing interference to neighbouring sectors.

Very high-gain narrow-beam antennas (e.g., 24 dBi+ panels or dishes) can achieve longer point-to-point distances but with a much smaller coverage footprint and more critical alignment. The RG-ANT20S-90 provides a balanced approach: substantial range for PTMP while retaining a useful sector width for multiple clients.

Omni antennas radiate in all directions and are excellent for localised coverage, but they are inefficient when trying to extend range or serve a large number of clients in a particular bearing. Sector antennas like the RG-ANT20S-90 concentrate energy, improving capacity and reach for sectorised base stations.

A key competitive advantage is its design synergy with Ruijie AirMetro radios and Reyee cloud management. For operators already in the Ruijie ecosystem, this reduces integration friction versus third-party antennas and improves monitoring and troubleshooting at scale. Physically, its IP55 rating and strong wind survivability put it ahead of cheaper, less rugged alternatives for exposed outdoor sites.

Customer feedback and real-world impressions

There are limited verified public consumer reviews specifically for the RG-ANT20S-90 at the time of writing. However, feedback commonly reported by installers and network operators deploying similar Ruijie Reyee sector antennas tends to highlight several recurring positives and pragmatic notes:

• Positive:Installers appreciate the included mounting kit and cabling which reduce time on-site. WISPs and campus IT teams report stable links at ranges consistent with the antennas 10 km working distance when paired with appropriate radios and line-of-sight paths.
• Performance:Operators note improved SNR and throughput versus older lower-gain sectors, particularly at the cell edge, and better suppression of vertical stacking interference because of the 7 vertical beamwidth.
• Durability:The IP55 enclosure and solid mechanical design receive positive mentions for resisting weather and wind on towers and rooftops. The specified surge and ESD characteristics are cited as useful when integrated with compatible radios and grounding practices.
• Considerations:Some customers remind prospective buyers to verify local frequency regulations and to consider professional installation for tower or rooftop mounts to ensure correct grounding and warranty compliance.

Conclusion why the RG-ANT20S-90 is a strong choice

The Ruijie Reyee RG-ANT20S-90 is a practical, well-rounded sector antenna for PTMP base-station roles where a balance of range, sector coverage and environmental resilience is required. Its 20 dBi gain and 90 horizontal sector create an effective compromise between coverage footprint and link budget, while the narrow 7 vertical beam helps manage inter-sector interference and improves throughput consistency.

For WISPs, campus networks, CCTV backhaul and municipal deployments seeking a robust outdoor antenna that integrates smoothly with Ruijie AirMetro radios and Reyee cloud management, the RG-ANT20S-90 presents a compelling option. The inclusion of mounting hardware and RF cabling, combined with a high wind survivability rating and surge/ESD specifications, reduces deployment friction and enhances operational reliability.

Before purchase and deployment, confirm local regulatory permissions for the 5 GHz bands in your country and consult your supplier on CE/UKCA status and any warranty or installation support options. Priced competitively for its category (suggested retail around $144.29), the RG-ANT20S-90 offers a strong mix of performance and practicality for professional outdoor wireless networks.
