[QUOTE="guest poster, post: 562607, member: 262401"] Those dimensions match a C120 Channel Master feedhorn & MTI LNB 'made up'. If that is the case it's a C120 not an LNBf. Is there a 50mm flange with small bolts/screws connecting the feed horn(tube-muzzle) to the (LN) block at the back? Anyway... the focal length should be closer than 53cm to the 'face'... the focal length is [B]'inside'[/B] the LNB's feed horn not at the face ... it's about 30-40mm in if you have got a C120.... or 49-50cm from the dish face to the face of the LNB's feed horn... then as recommended... fine adjust for best signal. Again... a picture would help. [/QUOTE]
