about a little:  Phased-array To stear them they usually use
adjustable delay lines (which I'm not an expert on).  But why I
replied is sort of off topic.  I think a flat array of phased
patch antennas might be the answer for a portable microwave
antenna (for AO-40 reception, or general microwave roving).  I
haven't played with patches, yet, but I think they average about
10 dB gain.  To receive AO-40 on 2401 you should strive to have
a minimum of 24 dBic ga
