Antenna placement
Best results are achieved when the antenna faces into the area where the
microphones are used.
Optimal placements for the Antenna are either below the ceiling in the middle
of the room facing down, or high on a wall facing into the room.
The antenna should not be placed flat, e.g. on a table or in a rack, similar to
the height the microphones are typically placed.
