and we found that the WTM4200 has 5.5db more system gain then the SIAE AP2 at 4096QAM which had better system gain then some of the other radios on the market. SIAE questions if Aviat is reporting correct numbers but I don't think they are incorrect either.... Even if Aviat's numbers are a bit exaggerated and there was only a 3db difference that's still a whole antennas size!
