Fixed Wireless Sector Antenna

The Mimosa Networks N5-45x4 is a 4.9–6.4 GHz sector antenna built for fixed wireless broadband deployments. It delivers 22 dBi gain with an additional 3 dBi from beamforming when paired with a compatible 4x4 MIMO radio. The dual-slant 45º polarisation and 45º azimuth beamwidth support high-capacity point-to-multipoint links. This 4-port unit is designed for tower and collocation sites requiring long-distance performance and noise rejection.

Compatibility And Mounting Checks

Verify that your radio supports 4x4 MIMO operation and provides four matching RF connectors for the antenna ports. Confirm the operating frequency range of 4.9–6.4 GHz aligns with your licensed or unlicensed band plan. Ensure the mounting structure can accommodate the antenna’s physical profile and the specified 2º electrical downtilt. Check that the 50 Ohm impedance matches your feedline and radio interface requirements.

Beamforming Gain And Port Isolation

The integrated beamforming capability adds 3 dBi to the base 22 dBi gain, extending usable range for subscriber links. A minimum front-to-back ratio of 43 dB enables spectrum reuse on the same channel in back-to-back sector configurations. Cross-polar isolation exceeding 30 dB and port-to-port isolation above 10 dB maintain MIMO stream separation. Maximum input power of 30 dBm per port sets the limit for connected radio output.

Questions about this item

Does the N5-45x4 include mounting brackets and radio cables, or must they be purchased separately?

The antenna has four N-type ports for connection to the Mimosa A5c 4x4 MIMO radio; mounting hardware and cables are not included with the unit.

Should I choose this 45° sector model or a wider beamwidth version for my deployment?

The 42° azimuth beamwidth focuses energy for long-distance links and high collocation density; a wider sector would reduce gain and noise rejection at the tower site.

What does the 22 dBi gain figure mean once the antenna is installed on a tower?

The 22 dBi gain combines the physical antenna performance with 3 dBi of beamforming from the paired A5c radio, delivering extended range and 43 dB front-to-back ratio for spectrum reuse.
