Precision WiFi instead of a watering can: The UMA-D Directional Antenna
Imagine the standard Antennas of your WiFi Access Point working like a watering can – they distribute the WiFi signal evenly in all directions. That's great for general room coverage. However, if you want to supply a specific, distant point like your garden shed or a workshop across the way, you need a laser beam. That's exactly what the UMA-D is: a highly specialized Sector Antenna that bundles the transmission power of your UAP-AC-M and precisely directs it where you really need it. The result is a stronger, more stable, and faster connection over distances that would be unreachable with standard Antennas.
The ultimate solution for a stable WiFi Bridge
The UMA-D is the first choice if you want to set up a reliable WiFi Bridge. In combination with two UniFi AC Mesh Access Points (UAP-AC-M), you build a stable point-to-point connection between two buildings – without expensive excavation for Ethernet Cables. Thanks to the high Antenna gain of 15 dBi in the 5 GHz band, even medium distances with clear line of sight are no problem for these 5 GHz Antennas. This way, Ubiquiti helps you reliably and performantly connect your entire property with the UniFi system.
Thoughtful Design for Easy Installation and Perfect Alignment
Ubiquiti has thought of everything with the UMA-D. The Antenna connects directly to the RP-SMA connectors of the UAP-AC-M. The real highlight, however, is the ingenious three-axis ball joint mount. It allows you to precisely adjust the Antenna after mounting it on a mast or wall – left, right, up, down, and even in rotation. This precise alignment is the key to getting maximum performance from a Directional Antenna and ensuring an absolutely stable connection, supported by robust Antenna Mounting Accessories.

Frequently Asked Questions (FAQ)
Which WiFi Access Point is the Ubiquiti UMA-D Antenna compatible with?
The UMA-D is specifically designed and optimized as an optional directional antenna for the Ubiquiti UniFi AC Mesh Access Point, model UAP-AC-M. This enhances your Ubiquiti Networks setup.
Can I use the UMA-D Antenna indoors?
Yes, although designed for outdoor use, the Antennas can also be used indoors without problems, for example in large warehouses or long corridors, to direct the WiFi Antennas signal specifically.
What does an antenna gain of 10 dBi and 15 dBi mean?
Antenna gain indicates how strongly the Antennas focus the signal in a specific direction. The UMA-D has a gain of 10 dBi in the 2.4 GHz Antennas frequency band and an even stronger gain of 15 dBi in the 5 GHz Antennas band. A higher dBi value means stronger focusing and thus a greater range in the main beam direction.
What is the difference between the UMA-D and the standard antennas of the UAP-AC-M?
The standard antennas of the UAP-AC-M are 2.4 GHz Omni-Directional Antennas, emitting the WiFi Antennas signal evenly in all horizontal directions. The UMA-D is a 5 GHz Sector Antennas or 5 GHz Directional Antennas, which concentrates the signal in a narrower, defined sector to cover a greater distance or to provide targeted coverage to a specific area.
Do I need to make a special setting in the UniFi Controller when using the UMA-D?
Yes, it is essential to select the 'UMA-D' model under 'Antenna Gain' in the device settings of the UAP-AC-M within the UniFi Controller. This ensures that the correct gain values (10/15 dBi) are used for calculating the permissible transmit power (EIRP), which is important for compliance with legal regulations and optimal performance of your Network.
Is the UMA-D suitable for a WiFi Bridge between two buildings?
Yes, the UMA-D in combination with two UniFi Access Points (UAP-AC-M) is a very good solution for building a stable WiFi Bridge Sets (Point-to-Point) over short to medium distances with clear line of sight, thus connecting two buildings to your Network.
