Yes, I will change all the nuts and bolts to stainless. The instructions state a focal length of 50 1/8 inches. My question was where is this measured from, Channel Hopper suggested 1 cm inside the lnb. I take it that this means 1 cm from the face where the feedhorn attaches. he also mentioned...
I didnt use a 3 leg setup because the manufacturers instructions showed 4 legs. Unfortunately with parts missing I had to try and work out what I needed. It does mean that there is limited lateral lnb adjustment, probably use plastic washers or have to make something else.
