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. 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.

CABLE SELECTION Cable 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 1/2wave antenna, the cardioid pattern provided by the PA805WB offers enhanced 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. PA725 UA825 UA850
