Case III:
Small Auditorium or Church
A.
1st Choice
Factor
2 Antennas on Ceiling
Equal
All of the transmitters are about the same distance to the closest antenna. If there is IMD interference it will be small
Distance
compared to the transmitter signal. This meets the design rule.
The antennas are separated so at least one antenna is always out of the transmitter antenna's null. There is also antenna
Diversity
redundancy and better transmitter coverage due to having two receiver antennas. This meets the design rule.
Line of Sight
All transmitters are in the line of sight of both antennas. This meets the design rule.
Cable Loss
Use low loss cable to assure total loss in each run is less than 15 dB to meet the design rule.
Range Loss
All transmitters are close to at least one antenna and have about the same gain to meet the design rule.
Transmitter
The setup is ideal, so set the power to 1mW for extended battery life and minimal interference with systems in near-by rooms.
Power
Rating
Expect excellent performance with small and large channel counts.

Distance
pared to the transmitter signals. Meets the design rule.
The antennas are separated so at least one antenna is always out of the transmitter antenna's null, provided the antennas

are mounted in front of where the transmitters will be used. This meets the design rule.
If the antennas are high enough on the wall to not be blocked by people or obstacles on the stage then this meets the design

rule.
Cable Loss
Use low-loss cable to assure total loss in each run is less than 15 dB.
Range Loss
All transmitters are close to the antennas. It meets the design rule.
Transmitter
Use 10 mW (or 25 mW) output power to assure pick-up through Presenter's bodies and stage obstacles.
