PA805SWB -- Passive Directional Antenna
General Description
SHURE PA805 DIRECTIONAL ANTENNA
The Shure PA805 is a directional antenna for increased range and reduced interference as compared to omnidi
rectional 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 an
tennas, 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.
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 in
tended coverage area.
3. Connect the other end of the antenna cable to the ANTENNA OUT of the Wireless Transmitter or Antenna
Combiner.
Always perform a "walk around" test to verify coverage before using a wireless system during a speech or per
formance. Experiment with antenna placement to find the optimum location for the PA805.
