Welcome to satellites forum,
To receive the Astra 2d UK spot beam (BBC, Channel 4 & ITV), in your region you'll most likely be better off with a 2.4M dish for reliable reception although some areas close by appear to pull this beam in with a smaller dish ie.1.8M
North, South and Eurobird beams can be received with a 90cm - 1.2M
See coverage map for 2d
