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.
f If you have electrically conducting surfaces in a room, make sure to position the receiver or the
antenna wall mounts so that such reflection effects are avoided.
f If you have a reflecting ceiling, this can be achieved by positioning the antennas closer to the
ceiling.
