I have to adjust the feedhorn and the scalar ring of a Zinwell lnbf.
Has the focal point to be 1/4" inside the mouth of the feedhorn, or this is correct only for a Chaparral feedhorn ?
In other words, every lnbf/feedhorn is different or 1/4 inch inside the mouth of the feedhorn is always correct ?
My dish is a Fortec Star FS6D, modified to perfectly fit a Jaeger 1224 EL (dual axis HH).
