Will installing a bigger aerial pull in the missing freeview channels ?
Well, that's what the TV aerial installers will invariably tell you....


If you can save money by putting the thing up yourself, and know how to align it correctly at the transmitter, maybe worth thinking about a high-gain aerial specifically tuned to the digital channels. Otherwise - well it's an expensive upgrade ... perhaps wait till the existing aerial blows down in a gale, as we did...
Incidentally, if you do suffer from poor reception, the picture doesn't break up into 'snow' in the way an analogue signal does. What happens depends on the design of the digital box: sometimes they pixellate the image when necessary. Ours freezes the image and drops the sound for a few seconds. Can be a nuisance, especially when you're recording!
