The Ubiquiti IS-M5 Shielded airMAX Radio with Isolation Antenna is a high-performance 5 GHz wireless bridge designed to provide superior noise immunity in congested RF environments. Engineered with a die-cast aluminium base and a sophisticated modular design, this radio is an ideal solution for urban deployments requiring high-density co-location and precise beam shaping.

Advanced Modular Design
One of the standout features of the IsoStation M5 is its interchangeable horn antenna system. By default, the unit includes a symmetrical 45° isolation antenna, but it can be easily customised with optional 30°, 60°, or 90° horn antennas. This allows network engineers to optimise the radiation pattern and elevation to meet specific environment needs, significantly reducing side-lobe radiation and improving the front-to-back ratio.
Superior Noise Immunity
The IS-M5 is built to excel where traditional sector technology fails. By using tailored antenna radiation patterns, the device spatially filters both in-band and out-of-band RF emissions. This increased noise immunity is vital for maintaining high throughput and stable links in crowded areas. The all-metal shielded radio base further protects the internal hardware from electromagnetic interference.
Efficient airMAX Technology
Utilising Ubiquiti’s proprietary Time Division Multiple Access (TDMA) airMAX protocol, the IsoStation M5 delivers real TCP/IP throughput of over 100 Mbps. Unlike standard Wi-Fi, this protocol schedules data into pre-designated time slots, eliminating hidden node collisions and maximising airtime efficiency. This makes it a scalable choice for both Point-to-Point (PtP) and Point-to-MultiPoint (PtMP) applications.
