Hi, Bob;
You may find that computerized design has given us better optimized
antennas, especially of the more complex antennas such as Yagis. Very
slight modifications give us trade offs of bandwidth, beamwidth, gain,
and f/b ratio. Each comes at the expense of others; what is best for a
given application depends upon the application. Go to Cebik's site for
many hours of study of this aspect of antenna selection. Get a copy of
his article in the latest QEX for some specifics.
Good luck es 73 de WOØW
