In order to archive a greater precision, you can tighten the feedhorn front disc leaving a thicker thread. In this way
the collimation rod will be more precisely aligned with the feedhorn axis. Now look where the collimation rod tip: it
should be approximately in the center of the parabolic antenna.
If, as in the image above, it’s not pointing to the antenna, you can use the 3 120° Allen screws to adjust the tilt.
Unscrewing 2 screws and tightening the opposite one, the collimation rod tilt can be adjusted slightly (enough).
Caution: do not over-tighten these screws. When adjusting the angle of the collimation rod, make sure that the
distance between the feedhorn and the parabolic antenna, is always between 80 and 81cm.
