I just bought and tested the FVW Yagi-UDA Remote Controller Antenna for the MA2. It is 5.8Ghz Signal Extender.
Flying from my balcony height of 97 ft. in a straight line to a totally clear and unobstructed eastern horizon, I have the following one best max range result for each method over 3 runs each. Both quoted ranges successfully returned home on RTH. One fully charged battery, light 9 mph cross wind partly cloudy skies, Std mode, 23mph, alt 355 ft. Connection lost and recovered several times on each trip, alt 325-375 ft.
Stock antenna: 12,331 ft.
Yagi antenna: 14,956 ft.
