General Description
The Shure PA805 is a directional antenna for increased range and reduced
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.
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 RG8X/U or equivalent.
2. Use antenna cable to connect the antenna to the ANTENNA OUT of the
Wireless Transmitter or Antenna Combiner.
3. Mount the antenna so that it points toward the intended coverage area.
Note: Using too many transmission antennas in one installation can reduce
performance. To combine PSM antennas, use a PA821 Antenna Combiner.
Selecting Antenna Cables
Use 50 ohm low-loss coaxial cable, such as RG-8U. Shure offers pre-termi-
nated antenna cables ranging from 6 to 100 feet.
NOTE: When ordering cables from Shure, select the low-loss "Z" models
(available for longer cables) when using frequency bands above 1000 MHz.
Cable Maintenance
To maintain top performance for antenna cables:
• Avoid sharp bends or kinks in the cables.
• Do not deform cables with makeshift clamps, such as bending a nail over
the cable.
• Do not use in permanent outdoor installations.
• Do not expose to extreme moisture.
Antenna Placement
Use the following guidelines when mounting antennas:
• Antennas and receivers must be from the same band.
• Mount antennas at least one wavelength (two feet) apart.
• Position antennas so there is nothing obstructing a line of sight to the
transmitter (including the audience).
• Keep antennas away from metal objects.
Important: 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. If necessary, mark "trouble
spots" and ask presenters or performers to avoid those areas.
