RF waves do not cross metal walls. The antenna must not be placed in an enclosure
forming a shield (metal cabinet, reinforced concrete wall, metal framework or wall, etc.).
Any obstacle located between the components of the system (transmitter / receiver /
receiver) will produce a loss of range.
Insofar as possible, the repeater antenna should :
be placed in the most appropriate location to be best seen by the transmission and
reception points,
be directed downward, upward, or horizontally, referring to the fact that the best radio
lobe is indicated on the diagrams given above.
be pointed directly or, if not possible, with a minimum number of obstacles between the
transmission and reception points.
It should never cross a wall, even an insulating wall.
