[QUOTE="Channel Hopper, post: 1021915, member: 175144"] The Ku band feed on the Prodelin - prime focus - dishes have no adjustment at the feed end, using single bolts only. Theoretically it would be impossible to get the boresight incorrect if all feed arms are exactly the same length but it can happen, for example if the reflector panel tolerances are out, or the dish has been de-installed and moved to another site. The informal adjustment can help in the event of a change of feed from that supplied by the manufacturer, technology does advance in dish design, beyond the 20+ year old files used to construct a complete 1304/1374 antenna, but as you say, it is overkill.
