EnGenius SN-ULTRA-AS Antenna Splitter

The EnGenius SN-ULTRA-AS is an antenna splitter designed for DuraFon 1X, DuraFon PRO, and FreeStyl communication systems. It takes the radio signal from one base station and distributes it to two external antennas, extending voice coverage into spots that a single antenna cannot reach.

By placing antennas in different wings of a building, on separate floors, or both indoors and outdoors, you can eliminate dead zones without investing in extra base units. Warehouse managers can stay connected from the loading dock to the mezzanine office. Hotel staff can move seamlessly between the lobby and the parking lot. Farmers who need clear communication in the barn and across open fields can run coax to each location and rely on a single phone system.

Installation is simple. Attach the splitter to the base station with a short coax cable, then connect approved antennas such as the EnGenius SN-ULTRA-AK10 or SN-ULTRA-AK20 kits. A rugged housing guards the electronics against dust and daily bumps, and its compact size lets you tuck it behind racks or above ceiling tiles.

The circuitry delivers more than 14 dB of isolation between ports to prevent feedback and maintain clear calls. Insertion loss stays below 4.5 dB, so most of the transmit power reaches each antenna, and the splitter handles up to 4 W of power with ease. Once installed, the SN-ULTRA-AS quietly expands the practical range of your existing EnGenius system and saves you from costly infrastructure additions.
