Thanks, Russ, for your observations.
If you are OK with linear polarization (is the antenna for WiFi use?),
I suspect a biquad would provide better illumination than a cantenna
or a patch. Not that the latter two wouldn't work, it's just they
aren't optimum for that f/D
Yes, WiFi. If need be, can't I just rotate the biquad feed by 90 deg. and
get
horiz. polarization?
Yeah, I see (via net search) that biquad fits nicely with a 0.7 f/D dish.
Thanks again,

Do you know of a web site where the offset dish f/D is defined? I am
familiar with the conventional (feed at the center) parabolic reflector f/D.
My question relates to my wondering if the TV satellite dish is a parabola
with the horn feed offset away from the focal point.
