Typically on a big dish, we mount the scalar ring to the legs and just center it for the focal point. Then we adjust the F/D by sliding the horn further or closer to the center of the dish leaving the scalar where it is on the struts that hold it.
From what I understand the ADL feedhorns are one solid piece and the throat of the horn will not slide.
You must do the f/d by using long bolts and jamb nuts on the scalar ring from the struts-Is this correct?
If so, then is there an ideal distance for a given dish, from where the end of the feedhorn is spaced from the scalar ring?
Then by adjusting the relationship of the entire assembly to find the best f/d could performance be enhanced?
Instead of just mounting the ring where it falls flush on the feed support struts.
