Ok so basically I got a tv without the leads all I have is a scart lead and an indoor aerial... the scart lead is connected to the digital box that you need to get digital tv now as it is all digital what else do I need like an outdoor aerial or something?
You will probably need an outside aerial, but in all cases the aerial lead goes into the aerial-in socket on the freeview box. Then you need an RF cable to plug in to the aerial-out socket on the freeview box which the plugs in to the aerial-in socket on the TV. Connect the TV to the freeview box with your scart lead and you should be in business.
Plug your indoor aerial into the back of your digital box. Use the scart lead to connect digital box to tv. Turn everything on and set up your digital box. Depending on your location you may be able to get some channels without an outside aerial.
