Rule of thumb for beam tilting for a reflector antenna with off-focus feed
I'm looking for a rule of thumb for the beam tilting of a reflector antenna when the feed has an offset relative to the focus. So basically something like focal length+feed offset equals x° of beam tilting. I'm assume that the exact tilting depends on illumination etc., but for the first rough design it would be very useful to have a rule of thumb.
Thanks
