1. The antenna must be installed before powering on.
2. Is, you should double check that the screws of the antenna and RF transmitter are tightened.
3. Because if the antenna is not installed or the contact is poor, the power amplifier will burn out.

1. You should install both two antennas on the air terminal.
2. It is best to use the transmitter antenna we configure for you, ensuring that the frequency and gain of the antenna are tested and verified.
3. The two antennas are best installed on both sides of the drone to ensure that the drone can still get the best signal when turning and maintain uninterrupted contact with the ground control station.

1. You should install both two antennas on the ground terminal.
2. It is best to use the transmitter antenna we configure for you, ensuring that the frequency and gain of the antenna are tested and verified.
3. The two ground wireless video data receiver antennas should be kept as far apart as possible.
4. They should be installed as high as possible above the ground to receive the signal from the drone transmitter.
5. The feeder cable is relatively long. For the convenience of packaging and transportation, it is bundled into a circle. Valós használatban, you must remember to unfold the feeder line. Do not let it remain in its original round shape, because this will invisibly create an electronic interference environment.

1. Igen, just output the standard PPM signal through the trainer port;
2. Or use the S.BUS receiver for communication.

1. Nem, a plane can only have one air unit transmitter. If you need it to support more cameras, please tell us to offer you a better solution.

1. P2P point-to-point devices can only install one ground terminal.
2. P2MP point-to-multipoint devices support multiple ground terminals.
3. If you have this requirement, please remember to tell us when placing your order and we can configure it for you.

1. Please check whether the antenna of the drone VTX is far away from the GPS to avoid blocking interference from the GPS.
2. The frequency band of 1.4G equipment is close to the GPS frequency band, so a certain degree of antenna isolation must be ensured.

3. LED5 (uplink indicator):
   1. When the light is on, it indicates that the link between the ground unit and the air unit has been established;
   2. When the light is off, it indicates that the link between the ground unit and the air unit has been disconnected.
4. LED6 (downlink indicator light):
   1. When the light is on, it indicates that the link between the air unit and the ground unit has been established;
   2. When the light is off, it indicates that the link between the air unit and the ground unit has been disconnected.
