Steve i think in this case size matters, we fitted a 1.9 famaval dish about 12 years ago on the roof in the corner. It is big and is ugly BUT it has given via several old sky boxes 12 years of uninterrupted tv, we get the same tv as back in england, you even get numerous local bbc news channels. You see a lot of these big dishes around and most seem happy, some neighbours use the smaller dishes and get the same reception, my only concern regards the signal strength with GA being close the limit, you pays your money and takes a chance.
