Key Features:

Sector Antenna


All the beamforming gain and ground coverage of a sector.
All the sidelobe rejection of a horn.

The Mimosa N5-45×4 is the industry’s first sector antenna to deliver the best of both worlds — incredible noise rejection and long-distance performance, with wideband 4.9–6.4 GHz operation for fixed wireless broadband. This 4-port, dual-slant polarization, 45º sector is designed for use with the Mimosa A5c 4×4 MIMO radio, delivering gain-enhancing beamforming for the best possible channel reuse, range and noise rejection at collocation and tower sites.

• Industry-Leading Front-to-Back Ratio for 2x Spectrum Reuse
• World-Class Noise Rejection
• Beamformed High-Gain for Long Distances
• Wideband 4.9–6.4 GHz Sector

 Reject Noise and Synchronize Overcoming noise at tower sites is key to scaling capacity. The N5-45×4 delivers industry-leading side lobe rejection and an unprecedented 43 dB front-toback (FTB) performance — the highest FTB ratio of any sector or horn antenna in the industry. When used in combination with the Mimosa A5c access point, there’s no higher performance tower solution to deliver full, 2x spectrum reuse.
 Wideband Operation Supporting 4.9 GHz public safety applications and multipoint licensed operation up to 6.4 GHz (where regulations allow), the N5-45×4 provides an additional 800 MHz of spectrum beyond the crowded 5.15–5.85 GHz unlicensed channels.
 Go the Distance The Mimosa N5-45×4 offers the best of both worlds — a long distance, high-gain sector with the superior noise isolation of a horn. Competitive sectors offer highgain, but fail to reduce side lobe and front-to-back noise. Symmetric horn antennas achieve good noise isolation, but typically offer lower gain and inefficient symmetrical ground coverage patterns.
 Compatible with Third-Party Radios In addition to the 4×4 MIMO Mimosa A5c, the N5-45×4 will support two concurrent third-party 2×2 MIMO radios operating on separate channels to double the coverage capacity at a tower site and avoid the congestion of the unlicensed 5 GHz band.
 Designed for Beamforming Paired with the 4×4 MIMO Mimosa A5c, the Mimosa N5-45×4 provides an easy-to-aim, 9º vertical beamwidth coverage area with a narrow, 4.5º signal and +3 dB gain per client. In the uplink direction, the A5c’s digital phasing works with the 4 port N5-45×4, adding +3 dB of receive gain.
