FPV camera transmitter

FPV transmitter long-range model is FPV1887. FPV camera transmitter has two types, analog video and digital COFDM digital video encoder and transmission. FPV1887 is the second type.

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.

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?
