I have a Freesat connection using a Sky mini dish, which was installed for previous house owners, and a new Bush receiver box. The reception on most Freesat channels is good but the BBC News channel  and BBC Parliament reception is awful. Any suggestions as to why this might be? I have two cables from the dish but am using one only. This may,or may not, be relevant.

andyfras.  Thanks for your reply. No I have not tried the other lead because, as I say, most of the channels have good reception and terminating the second lead would be a nuisance unless there is a logical reason why one lead would give reception on all freesat channels and the other lead not. Perhaps I had better give it a try however, failing any alternative
