MIMO directional antenna Ubiquiti AF-MPX8

The Ubiquiti AF-MPx8 MIMO directional antenna multiplexer lets you combine multiple airFiber X radios on a single 5 GHz dish antenna to increase throughput, improve noise immunity, and provide link redundancy. It uses precise GPS synchronization so connected radios share a common timing reference, enabling cohesive multi-Gigabit point-to-point bridging. The AF-MPx8 is compatible with most 5 GHz airFiber X and RocketDish antennas and can be pole-mounted for other configurations.

Advantages

The AF-MPx8 supports 4x4 or 8x8 MIMO backhaul configurations and enables quick, plug-and-play installation of multiple airFiber X radios on an existing dish. It allows use of channels of varying sizes — including adjacent channels without a guard band — and reduces tower footprint and costs by consolidating multiple radios on one antenna. Multiple carriers across different frequency bands deliver improved noise immunity and true redundancy. For integrated deployments, pairing with EdgePoint provides radio-link load balancing and enhanced reliability for fiber-connected sites.

Suitable for

• Multi-Gigabit point-to-point backhaul links
• High-capacity wireless network aggregation on towers
• Redundant links requiring improved noise immunity
• Upgrading existing 5 GHz airFiber X or RocketDish installations

Key specifications

• Manufacturer: UBIQUITI
• Model / MPN: AF-MPx8
• Frequency band: 5 GHz
• Supports: 4x4 or 8x8 MIMO configurations
• Mounting: compatible with most 5 GHz airFiber X and RocketDish antennas; pole-mountable for other antennas

How to use

Mount the AF-MPx8 onto a compatible 5 GHz airFiber X or RocketDish antenna using the provided hardware; if the antenna is not supported, attach the unit to a pole. Install the airFiber X radios onto the multiplexer according to the manufacturer instructions, connect each radio to the dish feed points, and verify GPS synchronization across radios so they share the common timing reference. Configure radio channels and bandwidths in the airFiber radios; adjacent channels may be used without a guard band when appropriate.

Recommendations

Use the AF-MPx8 with Ubiquiti airFiber X radios and compatible 5 GHz dishes for optimal performance. Pairing with an EdgePoint unit is recommended for radio-link load balancing and improved operational reliability in fiber-enabled deployments.
