P A805W B
SHURE PA805WB DIRECTIONAL ANTENNA
The Shure PA805WB is a directional antenna for use with Shure PSM
Wireless Systems. It features a log periodic dipole array and operates in
the 470 to 870 MHz range. When compared to an omnidirectional 1/2-
wave antenna, the cardioid pattern provided by the PA805WB offers en-
hanced coverage, improved range and reduced multipath interference
conditions.
The PA805WB can be mounted on a microphone stand or mounted to a
wall using the integral swivel adapter bracket.
NOTE: Using too many transmission antennas in one
installation can reduce performance. To combine PSM
antennas, use a PA821 Antenna Combiner.

INSTALLATION INSTRUCTIONS
1. Determine the length of cable required to connect the PA805WB
Antenna to the Wireless Transmitter or Antenna Combiner. Use
only as long a cable as necessary, because there is more power
loss with longer cables.
IMPORTANT: Always use low-loss 50 ohm cable, such
as RG-8X or equivalent. Shure UA825 7.6 m (25 ft.) or
UA850 15.2 m (50 ft.) cables are recommended.
2. Connect one end of the antenna cable to the PA805WB. Then
mount the antenna so that it points toward the intended coverage
area.
3. Connect the other end of the antenna cable to the ANTENNA OUT
of the Wireless Transmitter or Antenna Combiner.
NOTE: 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 for the
PA805WB.
