How was this possible (sky in other room)?

I had sky in my main room before and at the time I was also able to get whatever channel was being watched in the main room on a tv in a second room without any cabling between them. There was also no video sender or anything like that. The guy who installed it just seemed to tune it in. After awhile we got rid of sky but recently got it back but this installation guy did nothing like the first fella so we don't get the same sky in the second room.
I'm trying to get my head around how it might have been done before but it doesn't make sense to me. I want to get the tv in the second room displaying what's on in the main room and I imagine I'll run a coax between them. I'm just really curious as to how the original setup might have been working?

There must have been a cable, either coax. from the Sky box RF output or an AV cable. Or a video sender.

He probably just used already existing cables in the walls.

Had the same set up in my house, this is how it worked for me. The antenna cable goes into sky box and another cable carries the signal out to a distribution box. Your second tv takes it's feed from the distribution box which is carrying the sky signal.

So without a video sender (there definitely isn't a standalone one) he must have used cables? I'm pretty sure there's no distribution box either. I better have a proper look at where there might be cables so! Thanks for the response.
