Hi, hope i can gain some expert knowledge in this area. I have a 42" plasma tv with freeview built in, the picture is juddery and no matter what i do remains so, the picture with sky is smooth - i am informed that my signal to the freeview tuner is not strong enough. To this end i am looking at upgrading the loft ariel to an external one and cabling with a high quality cable such as kimber v20 or 30. Can anyone recommend an ariel to use? Also does high quality cabling make that much of a difference? Oh i live 3 miles from the transmitter. Thanks for any help offered.
