Recommendations on antenna mounting

Further important information on antenna usage
Reflecting surfaces
Electrically conducting surfaces (e.g. ceilings with metal constructions)
can reflect the RF signal.
►
The signal is reflected by the electrically conducting surface. At worst, the
blue signal and the red reflected signal are out of phase when they reach
the receiver so that the two signals cancel each other out.
▷ If you have electrically conducting surfaces in a room, make sure to po-
sition the receiver or the antenna wall mounts so that such reflection
effects are avoided.
If you have a reflecting ceiling, this can be achieved by positioning the
antennae closer to the ceiling.
Blocking effects from other transmitters
As with all wireless microphone systems, suboptimal positioning of trans-
mitters can lead to blocking effects. To avoid this, please follow these rec-
ommendations:
▷ Position DECT telephone or DECT access points at least 7 m from the
antennae.
▷ Position other wireless devices such as mobile phones at least 1 to 2 m
from the antennae.
▷ When transmitters are currently in use, you must not position any
other transmitters in the blocking area. If you must position them
there, switch them off.
