Shure UA860SWB

The UA860SWB from Shure is a passive wide band omnidirectional UHF antenna. It’s been designed to improve the reception of wireless microphone systems such as BLX4R, SLX, QLX-D, ULX-D, UHF-R and Axient Wireless Systems when used appropriately.
The UA860 is weather resistant and suitable for temporary outdoor use. However, long-term exposure to moisture should be avoided.
Installation
Connect the antenna to the receiver or distribution system using Shure antenna cables (or any 50 ohm, low-loss coaxial cable, such as RG-8U).
For cable runs exceeding 25 feet (7.6 meters), an in-line amplifier (Shure UA830) may be required to compensate for signal loss.
Cable Maintenance
To maintain top performance for antenna cables:
Avoid sharp bends or kinks in the cables.
Do not deform cables with makeshift clamps, such as bending a nail over the cable.
Do not use in permanent outdoor installations.
Do not expose to extreme moisture.
Selecting Antenna Cables
Use 50 ohm low-loss coaxial cable, such as RG-8U. Shure offers pre-terminated antenna cables ranging from 6 to 100 feet.
NOTE: When ordering cables from Shure, select the low-loss “Z” models (available for longer cables) when using frequency bands above 1000 MHz.
Antenna Placement
Use the following guidelines when mounting antennas:
Antennas and receivers must be from the same band.
Mount antennas at least one wavelength (two feet) apart.
Position antennas so there is nothing obstructing a line of sight to the transmitter (including the audience).
Keep antennas away from metal objects.
Important: Always perform a “walk-around” test to verify coverage before using a wireless system during a speech or performance. Experiment with antenna placement to find the optimum location. If necessary, mark “trouble spots” and ask presenters or performers to avoid those areas.
