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.
Antenna Placement
Use the following guidelines when mounting antennas:
•
Receivers, amplifiers, and other accessories must be rated for use within
the same frequency range as the antenna.
•
Mount antennas
at least
one wavelength (1.75 m) apart.
•
Keep antennas away from metal objects.
•
Position antennas so there is nothing obstructing a line of sight to the
transmitter (including the audience).
•
Place antennas as close as possible to transmitter, such as to the side
of the stage (instead of a front of house location).
•
For cable runs exceeding 50 feet (15 meters), an in-line amplifier (Shure
UA834) might be necessary to compensate for signal loss.
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.
