TIPS FOR ACHIEVING OPTIMUM PERFORMANCE
Maintain a line-of-sight between the transmitter and receiver antennas.
Avoid placing transmitter and receiver where metal or other dense materi-
als may be present.
Avoid placing the receiver near computers or other RF generating equip-
ment.
Avoid placing the receiver in the bottom of an equipment rack unless the
antennas are remotely located.
Use the proper receiver antennas.
Point the antenna tips away from each other at a 45 angle from vertical,
and keep them away from large metal objects.
Maintain a distance of at least 10 ft between the transmitter and receiver to
prevent overloading the receiver.
Do not obstruct the transmitter antennas with your hands.
Use the proper cable when remotely locating receiver antennas. For best per-
formance, use Shure UA825 or UA850 low loss coaxial antenna cable, or 50
low loss cable such as RG8.
Use Shure UA830 Active Remote Antenna Kit for remote antenna placement.
Mount diversity antennas at least
(60 inches) or more is preferred. This can be achieved by remote placement
of one or both antennas using Shure UA825 or UA850 low–loss coaxial
cable and a Shure UA830 Active Remote Antenna Kit. For multiple system
installations, use the Shure UA840 Antenna/Power Distribution System.
