For AO-40, many stations, I recall, used the R. Myers Communications L.L.C. Model SB-32 DXC 2.4 GHz Parabolic Antenna. Does anyone have the specs showing gain? Would like to see results of some actual gain testing . Could not find any results on Central States antenna measurements tabulations. . Thanks , any info , please reply off line.
