I now understand how a Transmitter works but... How does the TV Station get their feed to the Transmitter??

[GaryB]

It varies depending on the location of the studio & transmitter and the local terrain but many were originally linked by a high bandwidth cable. This has now been replaced in many locations by a microwave link.

Companies such as BT and NTL have various distribution networks. For example, the DTT (Freeview and D34 [ITV + Channel 4) networks are carried by BT on a dedicated network that carries the transport streams ready for broadcast.
For analogue channels, it usually depends on distance and a number of other factors. For example, Channel 4 london is carried to Crystal Palace on 270 Mbit/s SDI circuits but Channel 4 for the rest of the US is carried as a compressed (approx 9 Mbit/s) feed around the UK.
For smaller transmitters, Relay by Radio (Microwave or UHF) is often deployed.

Channel 5 analogue use Digital Satellite - It used to be one of the Intelsats - not sure of the current situation.

During heavy rain and thuderstorms it managed to totally freeze the broadcast from Winter Hill and many other txs for well over half an hour. They now have a landline link to Croydon.
