steve: I would say not, as it is the rest of the Yagi that induces the signal in the dipole, the aerial is not an aerial without them.
Whereas with a satellite receiver the dish only guides and focuses the signal on the LNB, it does not induce the signal as happens in a Yagi.
You could just point the LNB at the right bit of the sky and you would get a very weak signal.
Earthstation is what the original Goonhilly dish was called, and I suspect it probably also included the buildings and everything else.
You do see "dish antenna" but "aerial" is usually only used for non-dish receivers, even though "aerial" and "antenna" are technically the same thing.

Tom Fletcher: All aerials are "digital compatible", that gets back to the original point about it being a 8MHz wide UHF modulated radiowave.

David Haworth: If the BBC only have a stereo source then they send it out as 2.0 over the 5.1, ie left and right only, nothing in center, backleft, backright and sub (and also as stereo).
Not all programmes are available in 5.1, and the BBC rules forbid "messing" to create virtual 5.1.
There is no "hole in the middle" the sound is just stereo. I explained about about how to select your amp to change this if you don't like it by selecting the appropriate option.
A lot of programmes on ITV1 HD are not produced in 5.1, I don't know if they virtualize it, they have lower quality standards than the BBC.
It is not "wrong" in anyway to leave a stereo-sourced programme (or indeed a mono one) as 2.0.

martin: On 11th/25th May 2011 the Kirkoswald transmitter will provide a digital service. You will need nothing more than your existing aerial. You may need to disconnect your booster at this time. See Kirkoswald VP digital switchover date | ukfree.tv - independent free digital TV advice .

elizabeth: The transmitter has all the channels it will ever have. It is a public service transmitter and the commercial operators have declined to operate from it.

paul: Not easily. The "add channels" feature on the Sky box is awful and not really suited for this. There is a limit of 20 channels.
If you want to view non-UK channels, you will find this easier with a "generic" satellite receiver.

Edward: I'm not sure why Sky have removed their name from the channel, I guess it was probably dragging their reputation for quality television into the mud.
Oh yeah, sorry.

Tom Fletcher: The joys of the "red dot".
ONdigital bought a enough pups on that one to fill the Battersea Home for them.
Which, as it happened, was just over the road.
