質問: why can't my drone still fly more than 1000 meters after the controller was modified?
回答: after modifying the remote control and adding an alientech antenna, your drone can fly more than 100 meters but cannot fly more than 1,000 meters. this requires attention to the following reasons:1. please go to the hd setting page of the app and select the signal frequency band that matches the antenna. for example: if you buy a pro 2.4g antenna, you need to set the frequency band to custom-->2.4g and manually select the channel with low interference.2. please go to the hd setting page of the app; please set the image transmission quality to the lowest, for example: normal, 720p, smooth.3. please go to the hd setting page of the app. if there is a bandwidth option, please set the bandwidth to 10m.4. you need to pay attention to no obstacles between the antenna and the drone. the farther the drone flies, the smaller the angle between it and you and the horizon. trees, buildings, mountains, and people in front of you may obscure the signal. the radio signal is a kind of wave. although it has the ability to diffract, the intensity of the diffracted wave will be severely attenuated. sometimes, you need to increase your standing position or fly the drone higher to get a longer flight distance. learn more
