[QUOTE="ckrys1, post: 5835, member: 175163"] Can anyone tell me how crucial it is that the feedhorn points directly at the centre of my 1.2m prime focus motorised dish? I have recently had a new dish and lnb professionally installed and although it worked fine, visually the feedhorn was pointing at a point about 15cm from the centre of the dish. Reception was fine on all the satellites I would expect to receive, but I could only get sparkly analogue pictures, and no digital, on 26E and 42E(as mentioned on a previous posting). Having failed to get the installer back (wasn`t impressed with him), I succeeded myself in refixing the lnb/feedhorn to a better position, pointing to about 6cm from the centre. This definitely improved analogue reception at 26E and 42E, but unfortunately still not enough for digital. My question is should I get up on the roof again and somehow reinstall the feedhorn so it`s pointing exactly at the centre, or would I be wasting my time? Or should I just try it and see? I`m not that great at heights so wouldn`t want to attempt it unless there was at least some chance of improving things [/QUOTE]
