When you have fitted an upgraded 5.8Ghz antenna do you fit a ground plane under the SMA connector. Antennas fitted without a ground place are likely to be inefficient.
A small alloy plate under the the SMA may give more range.
Has this been tried.
The stock antenna has no ground plane I can see ?
Maybe this was done to limit the control range for some reason, FCC etc type approval ? K
