CM Modified Unwin beam.
CM This is the Unwin beam of Unwin1.nec, but modified by
CM removing one reflector and readjusting the remaining
CM reflector. It exhibits very high front/back ratio, but only
CM over a fairly narrow frequency range. The feedpoint
CM resistance is also much smaller than that of the original
CM two-refelector design Unwin1.nec. Only a few minutes were
CM spent adjusting the reflector; better optimization in one
CM respect or another could probably be made.
CM In practice, small imperfections in the antenna and
CM environment are likely to reduce the front/back ratio
CM somewhat from the value reported by the program.
CM See antenna notes for Unwin1 for more information.
