I have a free to air satellite receiver they cost from about £40 Aldi, Lidi
Screwfix and a load more set them from time to time. Mine has built in finder and an audio scream can be set to move dish to best signal.
Around 250 channels and of them about 80 worth looking at. Approx double to freeview however there is no set order and you the user has to arrange as you want them. Same as freeview with a PC.
The electronic program guide varies a lot and some boxes are useless as far as program guide goes.
Also teletext is hit and miss some work OK and some are completely useless I think as not really designed for UK.
There are some channels that are encrypted as not allowed to be shown outside UK. The Freesat system will allow you to watch an extra few channels that are encrypted this way and also the EPG and Teletext will work better but because they use sky's EPG (You make one off payment) it also will only receive programs within their guide. There is one program which transmits Elvis 24/7 which you can't receive with box set to use Sky's EPG but all programs will be assigned Sky's numbers so easier to find.
However Sky boxes do not go into proper stand-by. With my free to air box even when set to auto switch on at pre-set time when in stand by my meter shows zero current use. However the X Sky and current Sky boxes use very little less in standby than they use when running and of course if you switch off they will not allow timed recordings.
As a Sky+ user then I have to accept the power usage as no option but using free to air against free to view there is so little difference I would use free to air and use less power and lose EPG as shown in papers as they are cheaper to buy and use less power plus can also be used on other satellites as well as astra.
The good ones can even have wired connection to rotator so it auto turns dish to other satellites.
Does that answer question?
