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 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.
