You can also get digital TV through a satellite dish, probably fixed to the outside of your building.
The satellite dish could be your own or a communal one if you live in a block of flats. Indeed, sometimes, residents club together to arrange for satellite reception for everyone all at once. The installation can be done for you - but you may want to ask for the dish to be placed discreetly.
Note : There may be local rules about where you can put a dish or you may have to get permission from your landlord or freeholder. There are two options for receiving digital TV by satellite without a subscription.
For both, once you have paid the start-up costs for the dish and box, there is no further charge. With the Sky subscription service, you can get more than digital TV channels as well as digital radio stations and interactive services. Other satellite services also exist.

By broadcasting to orbital satellites, they are able to blanket large portions of a continent with a single signal. Most television satellites carry 24 to 56 transponders. Each transponder is capable of receiving, amplifying and broadcasting a compressed stream of data carrying multiple channels. Analog satellite systems can broadcast around 30 channels per transponder, while digital systems use compression techniques to carry up to channels on a single transponder.
Television transponders are designed to retransmit received signals at a different frequency than the uplink signal to avoid interference. The dish receiver that sits on top of the television customer's home is similar in many ways to "rabbit ear" television antennae.
