Yep all good accurate stuff. With one small additional option a Sky digibox without a viewing card. Without a card you can't see the Free To= View Channels (FTV), of the main stream ones this currently means Channe= l
4(*) and five. All BBC and ITV channels are Free To Air (FTA) and don't =need a viewing card in a Sky digibox.
You can get a Sky digi box, dish, LNB and cable form many sources (freecycle?) and DIY install. The card only can be obtained from Sky for= =A320 one off. You don't have to spend =A3150 one off and let a Sky installation cowboy knock great spalls off your brick work.
The other slight problem with not having a viewing card in Sky digibox i= s that the regional varaiations default to London but if you place a card =
from your area in the box it'll set the region correctly and remember it= until completely power cycled.
(*) Many (all?) of the other Channel 4 offerings are already FTA and I expect Channel 4 itself to become FTA soonish.
