FAQs

1) What is the AM-5G20-90 used for?

A 5 GHz, 20 dBi, 2×2 MIMO sector antenna for outdoor Point-to-MultiPoint (PtMP) base stations.

2) What radios is it compatible with?

It’s designed to seamlessly integrate with Ubiquiti Rocket M BaseStations. Other 5 GHz radios may be used if you provide suitable mounting and RF jumpers check bracket/connector compatibility first.

3) What is the beamwidth and why choose 90°?

It’s a 90° sector. Compared with 120°, a 90° sector concentrates energy more, offering higher link budgets and better SNR within a narrower coverage slice great for denser, longer-range sectors.

4) How many client devices can it serve?

Up to 100 airMAX clients can be connected to a single airMAX sector (subject to RF planning, throughput targets, and radio settings).

5) Does it support MIMO and dual polarization?

Yes 2×2 MIMO with dual-linear polarizations and remarkable cross-polarization isolation for cleaner links.

6) What is airMAX TDMA and why does it matter?

airMAX uses a TDMA protocol to schedule time slots, reducing contention/latency and improving throughput and fairness in PtMP deployments.

7) What’s the gain and operating band?

20 dBi gain in the 5 GHz band.

8) Is it weatherproof for outdoor use?

Yes built for outdoor deployments with weather-resistant hardware and weatherproof RF jumpers included.

9) What comes in the box?

AM-5G20-90 antenna, universal pole mount, RocketM bracket, and weatherproof RF jumpers.

10) How far can it reach?

Range depends on EIRP, client antennas, noise floor, Fresnel clearance, and alignment. With proper planning and alignment, it supports long-distance PtMP links. Use a link budget calculator for your exact scenario.
