When it comes to C-Band I may be old but not "Old School" So I'm looking for old knowledge about using Chap ortho feeds. When you mount the LNBs is there a particular orientation. They can be mounted one way or 180° the other. Also when orienting the ortho feed on the dish is one polarity always in the center and the other offset? I've noticed things put together in different ways and wondering is there a wrong way and a right way?
