The Shure UA221 Antenna Splitter/Combiner Kit includes two adapters that can be used as one-input, two-output or two-input, one-output passive antenna splitter/combiners for UC4, SLX4, ULXS4, ULXP4, U4S, U4D, UR4S and UR4D receivers.
The UA221 Kit lets you split an incoming signal into two outgoing signals or combine two incoming signals into one signal. Each kit includes two UA221 Splitter/Combiners, four coaxial cables, and attaching hardware.
The UA221 Splitter/Combiners are designed for use with Shure Model UA400 1/4 wave UHF antennas, UA820 1/2 wave antennas, and UA802/UA825/UA850/UA8100 50 ohm low loss antenna cable.
Shure recommends using UA820 1/2 wave antennas with UA221 Splitter/Combiners. The UA820 provides up to 3 dB of additional gain compared to standard 1/4 wave antennas. The additional gain compensates for signal loss in splitting applications.
