Shure UA860SWB User manual

General Description
The Shure UA860 is a passive wide band UHF omnidirectional antenna. The
UA860 is weather resistant and suitable for temporary outdoor use. However,
long-term exposure to moisture should be avoided.
Features
• Greatly improves reception of wireless signal
• Omnidirectional dipole reception pattern
• Includes stand adapter, thread adapter, a 61cm (2ft) coaxial antenna
cable, and a 7.6m (25ft) coaxial antenna cable
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-termi-
nated 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.
