Not quite sure if this is the right forum but...... Mrs BoF's tv doesn't get a great signal on some freeview channels. This means they break up and generally aren't watchable. Most annoyingly this includes the 'Dave' channel and so i am unable to watch Top Gear repeats and other such gentleman's programmes. The aerial is an oldish analogue one but is pointing in the right direction. I / we don't want to fork out for a new aerial, and she doesn't want satellite. Will one of those little booster boxes work or are they just a gimmick??? Cheers!
