We've got DirecTV in OH. We had DirecTV install a satellite dish at our TV home - we bring our receivers from OH when we come down to TV.
Antenna in TV is installed for free (roof-mount.....pole mount in the ground is extra) and we pay no additional monthly charges on our bill. We make a phone call to DirecTV when we arrive in TV - they switch our service address over to our TV address so we can receive the local FL stations out of Orlando. We call them again when we get back to OH so they can align us with the local stations out of Columbus.

They don't mention this feature explicitly in their marketing. But they are the people within the organization who handle it.
