Yes, most new TV's don't even have antenna connections!
I think I've mentioned it here but I'll repeat it anyway:
I once carried around an Apple ][e in a huge hard-side suitcase. At least when I secured a weekend layover (Sat morning through Monday evening) when I flew for FedEx. The hotel had "cable" TV's in the room, but the box still connected to the "Ant." connections. Soon after I connected the ][ via the TV signal adaptor, I had a knock on the door (despite the 'Do Not Disturb' sign). The hotel had noticed that the TV had "disappeared"!
I'm not sure how they thought a "guest" would get out of the building with the rather large, 80 pound, cathode tube TV! Better safe than sorry. Perhaps they feared they would be sued if the thief hurt his back while carrying the TV?!
