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 ¼ wave UHF antennas, UA820A ½ wave antennas, and UA802/UA825/850 50 ohm low loss antenna cable.
Shure recommends using UA820A ½ wave antennas with UA221 Splitter/Combiners. The UA820A provides up to 3 dB of additional gain compared to standard ¼ wave antennas. The additional gain compensates for signal loss in splitting applications.
