You use a TV aerial and a booster amp with 3 (usually 4) outputs. Each output goes to one TV socket.
Regardless of which 'group' TV aerial you need for your local transmitter, you might want to fit a wideband aerial to allow for Freeview/Digital Terrestrial channels moving all over the place in the near-ish future.
Many flats are putting the door entry CCTV camera onto the TV distribution system as it's cheaper than providing video entry phone handsets for all the flats.
Incidentally, you can get satellite dishes with a 4-output LNB so you could provide a satellite feed to each flat quite cheaply too, and avoid future tenants putting their own dishes all over the property. NB This is not the same as a Quattro output, which is designed for use with a Multiswitch for larger installations.
