Summary of Contents for ClearOne WS800

  • Page 1 Application Guide WS800 Wireless Microphone System Antenna Application Guide...
  • Page 2 ClearOne Extension Antennas Application Guide ClearOne’s digital technology supports much larger microphone systems than is possible with analog technology. It should be noted that marginal antenna designs may work well with smaller systems, but they can cause hits and dropout as the channel counts go up. On the other hand, a well designed antenna system delivers excellent performance with both big and small systems.
  • Page 3 Case I: Flexible Configurations Conference Room 1st Choice Factor Antennas In Drop Ceiling All of the transmitters are about the same distance to the closest antenna. The IMD product is small compared to the transmitter signal. It meets the design rule. Diversity The antennas are separated so at least one antenna is always out of the null.
  • Page 4 Case II: Split Flexible Configurations Conference Room 1st Choice Factor 4 Antennas In Drop Ceiling All of the transmitters are about the same distance to the closest antenna. The IMD product is small compared to the transmitter signal. It meets the design rule. Diversity The antennas are separated so at least one antenna is always out of the null.

The IMD product is small compared to the transmitter signal. This meets the design rule. Diversity The antennas are separated so at least one antenna is always out of the null.
  • Page 7 Separate the antennas sufficiently so at least one receives a strong signal. (3) Dipole Antennas: ClearOne systems are shipped with dipole (rabbit ear) antennas, but they are only recommended with small systems and only when they are in the line of sight. They provide only a minimal diversity.
  • Page 8 (5) RF Scan: Antenna Power Measument Run the ClearOne Remote software RF Scanner to verify the antennas and cables are working correctly. Each transmitter is represented by two green lines, one for each antenna. The received power from at least one antenna should always be between -40 and -60 dBm.

    Paint: The plastic case can be painted with non-metalic paint to match the decor. Outdoor Mounting: ClearOne extension antennas are designed for outdoor use, but they operate normally mounted inside a waterproof plastic box. Polar Pattern: ClearOne extension antennas have a 160 degree polar pattern. Ceiling mounted antennas typically cover the entire room.
