Hi, Guys how to find the "skew" zero position on a bullseye feed horn ? I have modified my bullseye by cutting the KU top part and attached a regular universal KU LNBF.

Interesting mod!
Usually peak the signal close to band center on highest (south) satellite. You want to get best signal from all transponders if possible, but some sats are a little off "kilter" so sometimes you have to compromise a bit.Otherwise it should work the same as it did before the mod. Think there is an arrow that points up (or down). If it's a Chaparral the instructions ahould have a picture; should be something on-line.
Hopefully your Ku will match skew with your C-band; or maybe you can adjust Ku seperately after peaking C-band on your modded feedhorn. Depends on the probe position.
