UA844plus SWB

Antenna Distribution System

General Description

The Shure Model UA844+ is an antenna distribution system that allows for the expansion of wireless microphone systems by

splitting one pair of antennas to multiple receivers. It also amplifies RF signals to compensate for insertion loss that results

from splitting signal power to multiple outputs. A single UA844+ system can support up to five wireless receivers. A maximum

of five UA844+ systems may be used in a two-tiered configuration.

retailer for help with selecting the right wireless accessories.

Selecting Antenna Cables

Use 50 ohm low-loss coaxial cable, such as RG-8U. Shure offers pre-terminated antenna cables ranging from 6 to 100 feet.

NOTE: When ordering cables from Shure, select the low-loss "Z" models (available for longer cables) when using frequency bands above 1000 MHz.
