Hi, My LNB is integrated with feedhorn. (its a ku-band LNBF)
This LNBF is installed on a holder (adjustble plastic ring) and this holder is connected to the dish by tripod.
The length of LNBF is about 15cm and its contain some parts, that are:
A circular muzzle in the front, a tube in the middle -or neck- (that is 7cm) and a square part in the back.
My dish focal length is 53cm and holder is matched on focal length when it is assembled.
Which part of this LNBF should be mount on the holder to save focal length? Frontal part and or middle part?
If your answer is middle part, dish to back of LNBF distance will be less than 53cm!
