Probably a stupid question, but .....

Why cant sky broadcast without the need of a dish?

How do you propose to collect the signal from the satellite & deliver it to your receiver then?

They don't own or use any terrestrial broadcasting equipment - only satellites in Space.

ha ha said it was a stupid question, was just thinking out loud, so what are upc doing that means no dish is needed.
plus all those sky stands in the shopping centers all over the place, how do they manage without a dish, again only thinking out loud.

different kind of broadcasting for other things like how radio do it or else by cable. in shops they have satellites

Think.

UPC needs a cable connected to each house. Extensive cabled network required.

Sky send a signal up to a satellite. If you're in range of said satellite then you get the picture.

To get the geographical rang that Sky serve, a satellite is the easiest way.

A properly kitted out apartment block or flats would have a tv distribution system fed from a single satellite dish & terrestrial aerial, with cables running to any number of tv points. No need for separate dishes & aerials.

This is effectively what UPC etc. do i.e. feed from a single point & distribute on a closed cable network.

Sky have 1 very expensive transmitter in space. The signal is blocked by walls etc so the receiving device needs to be outside where it can see the satellite.

RTENL have hundreds of transmitters on hilltops insted. In some places the signal is strong so an aerial in the attic will do. In some countries, especially cities there are so may transmitters and the signal is so strong people use rabbit ears regularly and portable TVs. In Ireland RTENL only broadcasts a fairly weak signal meaning they assume people will put up outside aerials if needed.

If Sky wanted they could make the signal so strong smaller dishes would be needed. In london the signal is stronger, hence in london people can use smaller dishes called Zone1 dishes. These seem tiny compared to the size needed for Ireland.

Normal music and talk radio is so strong people expect to get a signal on a car or indoor radio. Not many people have to resort to an FM aerial on the roof fed to a hifi with an aerial connector.

TV direct to mobile phones was tested in Ireland and is working in some cities, but not practical except for high population areas. Imagine if your phone had 20 or 30 TV stations wherever you went!
