[QUOTE="MikeO, post: 434299, member: 242334"] Hi Guys, I wonder if anyone can give me a bit of advise about fine tuning a feedhorn. Basically, I had a small feedhorn on my quad, but due to pixating probs in Cyprus every evening, I was advised that a larger feedhorn may help. So I trundled off to the local supplier and bought one. The swap over was easier than I hoped, I only had to remove the smaller scaler ring and put the bigger one on as the screw threads were the same. The rest of the feed horn was identical, so I though I wouldnt need to replace that bit, and make my life easier. But I have noticed that the reception is still poor, and if anything a bit worse now. I think maybe there needs to be a bit of fine tuning needed. Does the relative position of the scaler ring have a majour impact, ie if it is screwed on fully, partially, or just near to the aperture? Also, I would guess just by changing the scaler ring, I wouldnt have to change the position of the LNB, ie its focal distance wouldnt have altered, nor the skew angle. I am at a bit of a loss. I also dont know if the reception change also just coincides with the bad time of the year here. I have noticed however that the default transponder at times almost entirely loses the signal quality (drops to zero), but this is early in the day, when 2D reception is great. I have also started to get a little breakup of C4 during the day which I didnt notice before. Maybe I should stop tinkering and get someone in to check everything for me, but any advise would be greatly appreciated. Cheers, Mike [/QUOTE]
