TIPS FOR ACHIEVING MAXIMUM PERFORMANCE
• Maintain line-of-sight between the transmitter and the receiver
antennas. Avoid obstacles made of metal or other dense materials.
• Minimize the distance from transmitter to receiver. It is much better to
have the receiver near the transmitter and run the received audio signal
through a long cable than to transmit over long distances or use long
antenna cables.
• Use the proper receiver antenna. A 1/4–wave antenna can be used if it is
mounted directly to the receiver. If the antenna is to be located at away
from the receiver, use a 1/2-wave or other high-gain antenna. (This is
necessary if the receiver is mounted inside a metal enclosure or placed
at a great distance from the transmitter.)
• Mount 1/4-wave antennas with the tips pointing away from each other at
a 45° angle from vertical, and away from large metal objects. Use the
proper antenna cable for remote receiver antennas. For best
performance, use 50 Ω RG–58 coaxial cable, and use only the minimum
length necessary.
• Mount antennas at least quarter-wavelength apart––about 42 cm (17
inches) for VHF systems, although 1.5 m (60 inches) or more is
recommended. In installations with multiple systems, use a Shure
WA405 Antenna Power/Distribution system or WA470 Passive Antenna
Splitter. They will help minimize the number of antennas and reduce
interference.
• When using the SC1 body-pack transmitter with a musical instrument,
use the WA302 instrument cable.
