Mimosa A5x and Sector Antennas: Choosing Between the N5-45x2 and N5-45x4

When it comes to building high-performance fixed wireless networks, pairing the right radio with the right antenna is everything. One of the most popular radios on the market is the Mimosa A5x (100-00107-01), a compact, connectorized 2×2 MIMO access point designed for scalable, efficient deployments.

But which antenna should you pair it with? Two of the most talked-about options are the Mimosa N5-45x2 (100-00083) and the Mimosa N5-45x4 (100-00084) sector antennas. Let’s break down the differences so you can choose the best match for your network.

Mimosa A5x at a Glance

• 2×2 MIMO radio with dual RP-SMA connectors.
• Compact and cost-effective.
• Ideal for short to mid-range access deployments.
• Works best when paired with sector antennas that match its 2×2 configuration.

Option 1: N5-45x2 — The Perfect Match

The N5-45x2 is a dual-connector, 45° slant sector antenna designed specifically for 2×2 radios like the A5x.

Why it’s the best fit:

• Both connectors on the A5x plug directly into both connectors on the N5-45x2, no ports left unused.
• You get the full gain, beamforming, and polarization performance.
• It’s a clean and very simple setup.

Ideal for:

• Service providers looking for maximum performance.
• Straightforward A5x deployments without extra radios.

Option 2: N5-45x4 — More Capacity, More Flexibility

The N5-45x4 is a 4-connector, dual-slant 45° sector designed for 4×4 MIMO radios like the Mimosa A5c. At first glance, it might seem like overkill for the 2-connector A5x, and if you only plug in one A5x, you’re right: half the antenna will go unused.

But here’s where it gets interesting:

• The N5-45x4 can support two concurrent 2×2 radios operating on separate channels.
• That means you can mount two A5x units on one antenna, each taking two connectors.
• This doubles your capacity at the tower without doubling your antenna count, reducing tower load and keeping your deployment clean.

Ideal for:

• Operators looking to scale capacity without adding extra antennas.
• Improving CPE performance by doubling available channels and boosting overall throughput.

Which Should You Choose?

• If you’re running a single A5x: go with the N5-45x2, it’s the proper match and the most efficient option.
• If you want two A5x units in one sector (or plan to add more capacity later): the N5-45x4 gives you flexibility and growth potential.

Final Thoughts

Pairing radios and antennas isn’t just about connectors, it’s about strategy. The Mimosa A5x delivers outstanding performance when paired with the N5-45x2, but the N5-45x4 opens the door for higher capacity and future 4×4 deployments.
