The Shure UA221 Passive Antenna Splitter / Combiner Kit includes a pair of one-input, two-output passive antenna splitters, four coaxial cables, two BNC male-to-male adapters, and connecting hardware. Each UA221 splits an incoming signal into two outgoing signals. UA221 splitters are intended for use with Shure Wireless Systems. Use Shure UA820 1/2 wave antennas (shown in Figure 1) or Shure UA400 1/4 wave UHF antennas, and Shure UA802, UA825, or UA850 50 Ω low-loss antenna cable.

Key Features

• 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.
