Antennas
Active Antennas
TheantennaconnectorsontheULXreceiverprovide12VDCforactivecircuitantennas.
Caution: Use only Shure antenna accessories to ensure the best operation. Do not use splitters, combiners, or antennas that provide a DC ground, as this can
cause the receiver to function improperly.
Antenna Combiners and Accessories
The supplied antennas can be connected directly to the BNC-type ANTENNA connectors. However, optional antenna mounting
accessories from Shure can improve reception and reduce rack clutter. Use the following guidelines:
Antennas and receivers must be from the same band.
Mount antennas more than 40 cm (16 inches) apart.
Use Shure UA825 or UA850 low-loss coaxial antenna cable (or any 50 ohm, low-loss cable such as RG-8U).
Visit www.shure.com for more information on wireless antenna accessories.
