Mike, you haven't given much information about the loop (size,

Oops, I didn't mention anything about symmetry in that post.

Probably because I'm not sure how important it might be. So if it is an
issue, I'm all ears!

Mike, the symmetry issue is about whether you want the deepest nulls. A
gamma match is not likely to give you the best symmetry and hence the
deepest nulls.

You are talking about a smallish loop, and without modelling it, I wonder
if the gamma feed is as efficient say, as a inner feed loop.

You have gone to a lot of trouble to keep losses in the loop down, it
would be a pity to compromise it too much with the feed system.
