Rule 5: The two (diversity) receive antennas should be at least 3 feet apart.
In
fact, some locations benefit from even wider spacing if a LOS path is established
from at least one of the antennas to all points in the room.

These rules lead to some conclusions:
a) Smaller rooms (25 to 50 ft range) can get by with antennas set just about

b) To cover medium size rooms raise the antennas up. The 6 to 8 ft level should
cover to about 100 ft, depending on how complex the environmenmt is. See

Figure 4.
c) For very large rooms the antennas should be on booms (like a MIC stand) or
set in the catwalk, etc. See Figure 5.
