Mimosa N5-45x4 Sector Antenna 4.9-6.4 GHz 22 dBi Sector Antenna



The Mimosa N5-45x4 is the industry’s first sector antenna to deliver the best of both worldsincredible 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 4x4 MIMO radio, delivering gain-enhancing beamforming for the best possible channel reuse, range and noise rejection at collocation and tower sites.

  • Reject Noise and Synchronize
    • Overcoming noise at tower sites is key to scaling capacity. The N5-45x4 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 N5-45x4 provides an additional 800 MHz of spectrum beyond the crowded 5.15–5.85 GHz unlicensed channels.
  • Go the Distance
    • The Mimosa N5-45x4 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 4x4 MIMO Mimosa A5c, the N5- 45x4 will support two concurrent third-party 2x2 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 4x4 MIMO Mimosa A5c, the Mimosa N5-45x4 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 N5-45x4, adding +3 dB of receive gain.
