ЧЗВ
въпрос 1: Does it support 5.0-5.13Ghz?
Отговор 1:These system supports 1.429~1.445G
въпрос 2: I need at least a 30km range from air to ground for UAV.
Отговор 2:Our system supports it, it should use a 2W power amplifier, it is better to use the special long transmitter antenna and two higher receiver antenna.
въпрос 3: I prefer 6dib for the airside, and 4000feet operating height, ok? Sure. Is there a possibility to get bidirectional data?
Отговор 3: It supports.
въпрос 4: Is there a possibility to get bidirectional data?
Отговор 4: Then the transfer distance should be almost 20km, the bidirectional data doesn’t support 30km.
