Wiring – this object on the exterior wall

tv-antennaukwiring

black cylindrical object attached to exterior wall 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.

My first guess would be, since it is over a door, that it is an outdoor lighting fixture. It would have a cable like Romex or somthing about the size of an extension cord. enter image description here

Second guess would be an external feed to the utility company. Those look like little pucks and are usually about 2 inches in diameter. It will have a small cable (the size of an Ethernet or phone cable) and they use them to read an internal meter without having to enter the house. I couldn't easily find a photo.
