I was thinking that for every published or generic design maybe there could
be a kind of master list that you could consult.

ie like:
Rating
Antenna Gain F/B Bandwidth

OWA (5 ele) 3 3 5

Standard Yagi (5 ele) 4 3 2

DL6WU (10 ele) 5 6 2

DL6WU (15 ele) 6 6 2

But, you could just use the actual values I suppose. You would have in this
case three seperate tables, this one above if low to high on the gain
parameter.



I am not aware of such a list. It would certainly be useful.

Typically, a designer has a specific need and the optimization solves for that.
