This object is attached to the exterior wall of my three-year-old, estate built house. It sits immediately above the patio doors and internally, on the same wall, there is a black cable protruding from the wall whose connectors look similar to, but not the same as, coaxial connectors.
Is this a mounting point for a satellite dish? It seems to be oriented such that any dish would be facing the opposite direction to others that I can see around the estate. Does this matter? I've never had a satellite service before.
