What is an optimum horn?
Answer: A
An optimum horn has the flare and length chosen so that the gain from the larger aperture just balances the loss from the quadratic phase error, which fixes the aperture size for a given length. Making it longer for the same mouth would reduce the phase error but is often impractical. Perfect matching, equal beamwidths and zero phase error are all desirable and are pursued by other means. Optimality here is a property of proportions rather than of performance in any absolute sense.
