質問: how can i get the best distance in using the alientech antenna.
回答: please set the hd page in the app correctly before taking off. select the frequency correctly. for example, you use a 2.4g antenna, select the 2.4g frequency band, and fix it. if you choose the 5.8g frequency band or dual frequency, this will cause the 2.4g antenna to fail to enhance the signal but will cause the signal attenuation and reduce the control distance. set the real-time image transmission to the lowest (if there is this option). for example, common, standard, process, 720p, 360p, etc.). when the flying distance is getting farther and farther, the higher the quality of the image transmission will lead to the collapse of the transmission rate of the channel. this interrupts the signal connection. choose the channel with the lowest interference—the lower the channel curve or column, the fewer interference sources around. the low interference channel helps to improve the signal transmission distance and reception effect. note: if you want to get a longer distance, avoid using automatic and choose the manual mode. please visually check whether the object you need to photograph is visible or directly viewed? please choose a field with a wide field of vision to take off, and ensure that no obstacles block the signal in the direction of flight. as the drone flies farther and farther, the angle between it and you and the horizon will become smaller and smaller. for example: when the drone's flying distance exceeds 5km, the included angle is only 3°. this will cause short buildings or trees in front of you to block the signal. after the signal is blocked, there will be severe attenuation.
