The PBE-5AC-ISO-Gen2 features the "Dish Reflector Design". This leverages Ubiquiti's "InnerFeed" technology which integrates the radio into the feedhorn of the antenna, so there is no need for any cable, improving performance by eliminating cable losses. By providing increased performance with its faster processor and innovative mechanical design at a low cost, the Ubiquiti PBE-5AC-Gen2-ISO PowerBeam AC is extremely versatile and cost-effective. Please note that this unit requires two units to bridge from one to the other.
