Mimosa N5-45X4 45-Degree Sector Dual-Slant Antenna, 22 dBi 4.9-6.4GHz Beamformi

The Mimosa N5-45X4 is a wideband, 4-port, 4x4 MIMO sector antenna engineered for high-density, high-interference fixed wireless access deployments at tower and colocation sites. Operating across 4.9–6.4 GHz, it covers the 4.9 GHz public safety band, licensed multipoint spectrum up to 6.4 GHz, and the crowded 5.15–5.85 GHz unlicensed channels from a single hardware platform. The 4-port, dual-slant 45° polarization architecture is purpose-built for use with the Mimosa A5c 4x4 MIMO access point, enabling digital beamforming that adds +3 dBi of gain in both uplink and downlink simultaneously. An industry-leading 43 dB minimum front-to-back ratio — achieved through metallized end caps and a precision-engineered backplane extrusion — provides exceptional noise isolation and enables full 2x spectrum reuse at co-located tower sites. The antenna also supports two concurrent third-party 2x2 MIMO radios on separate channels via any two of its four N-female ports, maximizing site capacity without requiring a Mimosa radio. The UV-stabilized outdoor enclosure is rated IP55 and survives wind loads up to 200 km/h (125 mph), while the galvanized steel dual pole mount accommodates poles from 38 mm to 90 mm with ±20° mechanical tilt adjustment.

Key features & benefits

• Wideband 4.9–6.4 GHz Operation — A single antenna covers the 4.9 GHz public safety band, licensed multipoint frequencies up to 6.4 GHz (where regulations permit), and all standard 5 GHz unlicensed channels — eliminating the need for multiple sector antennas at multi-band sites.
• Industry-Leading 43 dB Front-to-Back Ratio — Metallized end caps and a precision-engineered backplane extrusion deliver a minimum 43 dB front-to-back ratio, enabling full 2x spectrum reuse at colocation and tower sites and dramatically reducing self-interference from adjacent sectors.
• +3 dBi Beamforming Gain with Mimosa A5c — Paired exclusively with the Mimosa A5c 4x4 MIMO access point, the 4-port architecture allows digital phasing to add +3 dBi of beamforming gain in both downlink and uplink directions — raising effective gain to 25 dBi and adding +3 dBi receive gain per client in the uplink.
• Dual-Slant 45° Polarization with Superior Isolation — The dual-slant ±45° polarization scheme delivers greater than 30 dB cross-polar isolation and greater than 10 dB port-to-port isolation, supporting simultaneous independent transmission paths and reducing co-channel interference in dense deployments.
• Third-Party 2x2 MIMO Radio Support — In addition to the Mimosa A5c, the N5-45X4 supports two concurrent third-party 2x2 MIMO radios operating on separate channels — effectively doubling coverage capacity at a tower site using a single antenna structure and avoiding congestion in the unlicensed 5 GHz band.
• Precision Ground Coverage Pattern — A 9° vertical beamwidth with 2° electrical downtilt and a 45° azimuth sector (42° at 3 dB) provides an asymmetric ground coverage pattern optimized for tower-top installations, maximizing client density at ground level while minimizing wasted upward radiation.
• Ruggedized Outdoor Enclosure with IP55 Rating — The UV-stabilized engineered polymer enclosure is rated IP55 for outdoor deployment and is tested for wind survivability up to 200 km/h (125 mph), with an operating temperature range of -40°C to +55°C for reliable year-round performance in demanding environments.
• Flexible Galvanized Steel Pole Mount Included — The included galvanized steel dual-arm pole mount accommodates poles from 38 mm (1.5") to 90 mm (3.5") and provides ±20° of mechanical up/down tilt adjustment, allowing precise beam alignment without additional hardware.
