After a while on google and forums dx sought to have it I managed a prime focus lnb from China to buy ..
After remove the Inverto twin LNB feedhorn adf 120 to fit the holder the new Lnb fit not well. Then i found a solution to fit the new lnb on the dish bracket.
After replace the new Primefocus Lnb the adjustment with my spectrum analyzer Trimex 3500 results were very good, I've never received so much Nile sat
with fairly cloudy sky
