My Patriot feedhorn had arrived and got it with an Invacom quadconfirmed at the focal point and noticed that due to the combination of the Patriot shivering feed and high cross-polarizationthe signal from the Invacom Quad lnb is cleaner and therefore the threshold of the Clarctech 5100c works better;)I am also curious if you replace the round pipe of modding LNBs with 4 side 19 mm with a stronger signal.I tried the spreadsheet (thanks to A33) to determine the illumination angle with Fibohoek 77 degreesaccording to the drawing of Spreitje, very handy! ;) The Patriot feedhorn of 0.6 has according to the spreat sheetan illuminating angle of + - 90 degrees and over illuminating the Fibo, this also applies to the Inverto feedhorn, butthe reception value compared to that are very good. Also weak signals on the dm 920 of 3 db are without blocksI often read that a larger feedhorn does not matter much with regard to signal value, yet I think of the knowncardbord video on ytube "making a cardboard feedhorn" that there is indeed more signal than justa larger dish that not everyone can or may place .. There are also larger primfocus feedhorns on the marketwith 7 rings only a pity that there are no specs ..Maybe it is an idea for Trust to make feedhorns on the lathe, I'm still looking for feedhornsto experiment with an illumination angle of 77 degrees and an f / d of 0.715 according to the spreadsheet ..Nice back to the hobby now ..</blockquote>
