General Description

The Shure UA221-RSMA is a bi-directional splitter/combiner which can be used to route the RF signal from a single antenna to two inputs, or to connect two antennas to a single input.

Important Compatibility Information:

  • UA221-RSMA splitters are intended for use with Shure wireless systems which operate between 700 MHz and 2.7 GHz
  • Use with reverse SMA cables only
  • The splitter is not compatible with the UA846 Frequency Manager
  • The splitter blocks DC power
