The Shure UA221 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. The UA221 Antenna Splitter/Combiner Kit includes:
UA221 splitters are intended for use with Shure Wireless Systems. Use Shure ½-wave or directional antennas and Shure 50 Ω low-loss antenna cables when configuring the wireless system.
| Model | Frequency Range | Pass DC/Block DC |
| UA221 | 10-1000 MHz | Block |
| UA221-C-J | 10-1000 MHz | Pass |
| UA221Z | 1000-2000 MHz | Block |
| UA221Z-C-J | 1000-2000 MHz | Pass |
Use two UA221 Splitters and the supplied BNC male-to-male adapters and coaxial cables to split the RF signal from a single pair of antennas to the antenna inputs of two receivers.
Note: Antennas must be compatible with the operating frequency range of the receiver.
In this configuration, use UA221 or UA221Z, or ensure the receiver's DC bias is disabled.
When using powered antennas, use UA221-C-J or UA221Z-C-J.
| UA221/UA221-C-J | 10 MHz-1000 MHz |
| UA221Z/UA221Z-C-J | 1000 MHz-2000 MHz |
