What is the antenna gain of the Ubiquiti UMA-D?

The UMA-D provides 10 dBi gain at 2.4 GHz (2.4-2.5 GHz) and 15 dBi at 5 GHz (5.1-5.9 GHz), optimized for 802.11ac mesh applications. This directional gain focuses energy for better range and throughput versus omnidirectional antennas.

Which access point is the UMA-D compatible with?

Designed specifically for the UniFi AC Mesh AP (UAP-AC-M) using (2) RP-SMA connectors for direct attachment. It expands coverage with custom pattern shaping in dual-band mesh networks.

What are the beamwidth specifications?

HPOL, VPOL, and elevation beamwidths are 90° at 2.4 GHz and 45° at 5 GHz. This enables broad coverage at 2.4 GHz and focused high-capacity cells at 5 GHz, with max VSWR 2.5:1.

Is the UMA-D suitable for outdoor use?

Yes, encased in outdoor UV-stabilized plastic for weather resistance. Supports indoor/outdoor deployments with wall/pole mounting kits and three-axis ball joint for precise aiming.

What are the physical dimensions and weight?

Measures 201.3 x 128 x 32.5 mm (7.93 x 5.04 x 1.28 in). Weighs 400 g (14.11 oz) without mount, 480 g (16.93 oz) with mount, making it lightweight for installations.

What polarization and isolation does it offer?

Dual-linear polarization with cross-pol isolation of 25 dB at 2.4 GHz and 30 dB at 5 GHz. This minimizes multipath interference and improves signal quality in dense environments.
