We moved out standard non-HD Sky Digibox to the new annexe recently. That room is quite far from the Dish and the Sky Guy had to put in a very long (over 100 feet) cable to connect it to the box. As a result, the picture and to some extent the sound quality are poor, despite a good resolution TV. Maplins have an in-line satellite signal amplifier that is supposed be useful for such cases and boasts 20dB gain. It is economical at £12 and I am thinking of getting it (or a similar device depending on your suggestions). Plase advice if this booster really does improve the AV quality or if there are better options.
