Recessed signal-receiver mounting system for a building structure and associated methods

A method for mounting a pair of signal-receiving devices in a recessed position within a building surface comprising the steps of:

• positioning a base housing behind a building surface, the base housing having a wall defining an inner chamber, the wall having a first opening in a front thereof and a second and a third opening therein, each of the first, the second, and the third opening leading into the inner chamber, the base housing positionable behind a building surface;
• positioning a secondary housing behind the building surface and adjacent the base housing, the secondary housing having a wall defining a closable interior space, the wall having a first aperture therethrough into the interior space positionable in communication with the base housing second opening, the wall further having a second aperture therethrough into the interior space, the second aperture in spaced relation from the base housing wall;
• positioning a first signal receiver, as a part of the wall defining the closed interior space, within the secondary housing interior space;
• connecting the first signal receiver to a first signal carrier within the secondary housing inner chamber;
• positioning a second signal receiver terminating within the base housing inner chamber;
• positioning a second connector adjacent the third opening;
• and
• connecting the second connector to a second signal carrier within the base housing inner chamber wherein the second signal carrier is distinct and different enough from the first signal carrier to be non-interchangeable with the first signal carrier.
