According to the manufacturers’ spec sheets (SureCall, RFI, Wilson), here is the nominal gain for each antenna in dBi per frequency in MHz:
SureCall only lists one gain value in their spec sheet; they don’t break it down by frequency. Their spec sheet also doesn’t say if 3.5 dBi is nominal gain or peak gain.
Based on the available data, the RFI 38″ Q-Fit antenna has the best performance, followed by the SureCall (if their figure is nominal gain), then the Wilson.
