just red a post about adjusting the scaler ring in the feedhorn
ofcorse we donot have any kind of feedhorn on sail - all we have is a cheepe chinees old tec lnb with scaler ring all in one piece
so we try to improve the recepition by modifaing a good lnb like the inverto black ultra with a very good rersult
but we do not know much about bandwidth or how mush should the ring be away from the lnb
how many scaler ring 3 rings or 4
i have tried both and olso tried long lnb and shorter one
but should it be a scintific method to do that rather than do it by trail and erorr
here is a pictures of one of my lnb ( inverto ) there is some other modified ones but a cheep chines one
the dish hasa very poor surfacc - its a local 220 cm prime foucus made in 2003 by an egyptian company
this is the dish - ofcorse the extra paneles doest do any good in ku band but in c band does have some 4% to 5% increse in SNR
