I recently took my Sony Freeview box to my parents house to see if they could recevie the service. My reception in SW London/Surrey is virtually perfect on all channels. My parents live in Sevenoaks, Kent and the Freeview site says that the service is not available there. However, when I set the box up it achieved perfect reception on all the channels that it picks up, but does not pick up some of the channels at all (including ITV1/2, C4 & C5). I know this is not a problem with my box as it picks up all of these channels at home. I have tried a plug-in signal booster, but is there anything else I can try to improve the signal?
