SHURE PA805 DIRECTIONAL ANTENNA
The Shure PA805 is a directional antenna for increased range and re-
duced interference as compared to omnidirectional 1/2-wave antennas.
The PA805 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 PA805
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 PA805. 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 PA805.
