Ubiquiti UMA-D UniFi Mesh Dual Band Dual Polarity 802.11ac Directional Antenna

The Ubiquiti UMA-D is a professional-grade dual-band directional antenna designed to enhance and extend your UniFi Mesh network. Specifically built for compatibility with the UniFi AC Mesh AP (UAP–AC-M), this antenna delivers high gain, dual-polarity performance and weather-resistant durability, making it an essential upgrade for demanding outdoor or directional WiFi deployments.

Whether you’re working with Point-to-Multipoint (PtMP) installations, directional site coverage, or signal extension, the UMA-D provides precision signal shaping, stronger reception, and stable performance across both 2.4GHz and 5GHz bands.

Features & Benefits

Dual-Band 802.11ac Support

Optimized for 802.11ac networks, the UMA-D supports both:

• 2.4 – 2.5 GHz band with 10 dBi gain

• 5.1 – 5.9 GHz band with 15 dBi gain

This allows for strong, reliable connectivity across a wider frequency range and higher speeds.

Dual Polarity for Reliable Performance

The dual-linear polarisation improves signal penetration and stability, especially useful in congested environments or when aiming at specific client areas. It also helps to reduce interference and multipath issues.

Directional Radiation Pattern

With a focused directional beam:

• Vertical Beamwidth: 90° @ 2.4GHz, 45° @ 5GHz

• Horizontal Beamwidth: 90° @ 2.4GHz, 45° @ 5GHz

• Elevation Beamwidth: 90° @ 2.4GHz, 45° @ 5GHz

You get precise coverage with less signal waste and better control over your deployment area.

Ball Joint Mount for Precision Aiming

Mounting is made easy and flexible with the included ball joint mechanism, allowing:

• Accurate directional aiming

• Support for pole mounting (38–75mm diameter) or wall mounting
  This makes it perfect for temporary and permanent outdoor mesh installations.

Built for Harsh Outdoor Conditions

Encased in UV-stabilised plastic, the UMA-D resists degradation from sunlight and weather exposure.
Rated for wind speeds up to 125 mph, it is a rugged antenna suitable for outdoor deployments in harsh NZ environments.

Frequently Asked Questions (FAQs)

Q1: What is the Ubiquiti UMA-D used for?

A1: It’s a directional antenna designed to boost signal strength and focus wireless coverage when used with the UniFi AC Mesh Access Point (UAP-AC-M).

Q2: Is this antenna compatible with other UniFi products?

A2: The UMA-D is specifically designed for the UAP-AC-M. It uses (2x) RP-SMA female connectors, which may be compatible with other radios, but optimal performance is achieved with the intended device.

Q3: What kind of gain does the UMA-D provide?

A3: It delivers 10 dBi gain on 2.4 GHz and 15 dBi gain on 5 GHz, making it ideal for long-range directional setups.

Q4: Can I mount it outdoors?

A4: Yes, it is built with a UV-stabilised plastic housing and rated for wind speeds up to 125 mph, making it perfect for outdoor environments in NZ.

Q5: Does it support both wall and pole mounting?

A5: Absolutely. The ball joint mount supports precise aiming and is compatible with poles from 38–75mm diameter or can be wall-mounted.

Q6: What does dual polarity mean?

A6: Dual polarity (or dual-linear polarisation) means the antenna transmits and receives both vertical and horizontal signal polarities, improving signal quality and resilience.
