Hello alll ,
I wish some one just little see inside the lnb ,
there was 2 (two) a needle (dipole antenna) different axis H and V work on frekuency Ku band...
Maybe change that dipole (needle antenna) with patch pcb antenna give more db gain...

I was a couple year learning hfss and find that dipole (needle antenna) only 6-8 db gain ,
and someone technician installation Parabolic said that if you try to cut a mm( millimiter) maybe had some different result... gain
increase or decrease . he said trial and error...

patch pcb antenna work on expensive LNB or Monoblock LNB...
with patch antenna inside give 32db to 60db~ gain but hard to built because FR4 or pcb thickness in my country 1mm~ dual layer pcb...

I just only simulated ...
