[QUOTE="Channel Hopper, post: 836697, member: 175144"] Roughly 1cm inside the feedhorn. Boresight is both centralising of the feed, ensuring the distance to the reflector circumference is equal in all directions, and the path from the LNB, through the feedhorn and down to the exact centre of the reflector is a straight line. One of those small keyring lasers is especially good at seting the boresight up as they usually fit into the feed and the button is activated at the same time. [/QUOTE]
