5.0 GHz Shielded CPE

The Ubiquiti Networks IS-M5-US is a shielded airMAX customer-premises radio operating in the 5.0 GHz band. It targets installers who need a compact, all-metal unit with an interchangeable isolation antenna horn for point-to-point or point-to-multipoint links. The integrated radio base and modular horn allow beam-shaping to match specific deployment requirements.

Sustained throughput and co-location

The airMAX processor delivers up to 150+ Mbps throughput under continuous load rather than brief bursts. Asymmetrical horn options at 60° and 90° provide naturally attenuated side lobes and extremely low back radiation, while symmetrical 30° and 45° horns support dense cluster sector installations without sacrificing gain.

Industrial temperature range and PoE power

The die-cast aluminum enclosure operates from -40 to 70° C (-40 to 158° F) with passive cooling and no moving parts. A 24V 0.5A Gigabit PoE adapter supplies power and data over a single 10/100/1000 Ethernet port, simplifying cabling on poles or towers where AC power is unavailable.

Questions about this item

How much heat can the IsoStation M5 handle during continuous outdoor operation?

The unit is rated for an operating range of -40 to 70 °C, so it stays functional through extreme daytime heat and sub-zero nights.

What cabling and power gear must I already have to install this radio?

You need a Cat5e or better Ethernet run to the single Gigabit PoE port and the included 24 V 0.5 A PoE injector for power.

Will the 30° symmetrical horn work alongside older 5 GHz sectors on the same tower?

Yes, the symmetrical 30° and 45° horns are designed for cluster sector installs with high co-location density and low side-lobe radiation.
