[QUOTE="Coviello, post: 511050, member: 175681"] Reading again your message I realized that you had been doing test with a (non-mesh) 3.7m Prodelin. The original feed of my 3.35m Prodelin was absolutely inadequate and I replaced it with an Invacom Adjustable feedhorn C120 for prime focus antenna. Actually, I later replaced this with its "Cyprus version" (larger with many rings) which gave me some more improvements. Since your (and my) dish is excellent, to get the best performance you have to be very accurate when putting the feed: use laser-pointer to find the exact central position of the feed; use some trick to find the best focal distance (it might not to be the same you find in the manual) a variation of 0.2 mm could make a difference. I used all these idee to improve the performance of my Prodelin. Unfortunately, no trace of Astra2d in Potenza. But Central Italy, you can do it. Central Italy is not too far from Potenza, and I would be happy to show you my Prodelin if you visited me. Coviello [/QUOTE]
