What setting can I configure via the transmitter parameter configuration board tool?
3 sets of FPV camera transmitters with one extra transmitter parameter configuration board tool
3 full set of the FPV wireless video transmitter and receiver with one TX antenna and two RX antenna.
There are two cartons, 40x30x21cm 4kgs and 96x60x12cm 5kgs. Because the volume of the two cartons of goods is relatively large, the transportation company usually charges 12 kilograms.
One set of FPV transmitters and receivers, with an 80cm receiver antenna and one parameter tool for the transmitter.
Wireless Video Transmission is one of the important components of FPV. FPV means first-person vision. To realize the first-person view of the aircraft, it is necessary to use the Wireless Video transmission system to transmit the living video from the FPV camera back to the pilot’s glasses/screen.
From the perspective of transmission mode, wireless video transmission is mainly divided into two types, one is analog video transmission, and the other is digital video transmission.
Analog video transmission has been developed for a long time and has great advantages in terms of delay. The delay is low, so it is widely used in racing and pattern flying.
Digital Video transmission is a new technology, with low latency, longer transmission distance, and clearer images with HD resolution.
The wireless video transmission system is mainly divided into two parts: the receiving end and the transmitting end.
The transmitting end is a camera and video transmitter installed on the aircraft. The camera converts the captured picture into an analog or digital signal and transmits it to the wireless video transmitter, and the transmitter transmits the camera signal through radio.
The receiving end is responsible for receiving and displaying the signal on the screen.
We had a distance of 3 at first, and then after the settings, we were able to improve the video to 10 km, but then the picture disappeared again. We put the antenna vertically up and placed it in the tail of the plane, the picture improved, but we haven’t flown further than 20 km yet. And our goal is 40 km or more.
Do you have any pictures of the parameters on the receiver during flight and the installation pictures of the UAV video transmission?
I need to know the height of the antenna and the flying height of the drone to determine what means to use to increase the flying distance.
I am interested in video transmission for an fpv drone, CVBS at 30+ km, I also need radio telemetry at the same distance. Is it possible to connect the receiver to the Skyzone glasses?
We have fpv transmitter and receiver, the receiver has HDMI and CVBS output to the monitor. You can connect with a glasses monitor if you need it.
Fpv1887 supports 3W 55km, so 30km is no problem
We also have radio telemetry, vcan1878 추천.
Why my transmitter programmer is frozen on the power-on screen?
Because the transmitter and transmitter programmer (transmitter parameter configuration board tool) both need to power it on.
If I need to add a relay between the transmitter and receiver, there are two frequencies from the transmitter and receiver. One frequency is 860Mhz. Which frequency can I choose for the other one?
I recommend choosing a frequency between 200Mhz-700Mhz to avoid interference.
I suggest adding the filter to the repeaters, transmitters, and receivers to reduce frequency harmonics and interference between frequencies.
Could you please change the position of the transmitter RF antenna from a 45-degree oblique angle to a flat angle?
예, we can customize it for you. Please tell us when placing your order.
