A repeater for FPV ensures stable communication between the operator and the drone, especially at large distances and in difficult conditions. It also amplifies the signal and helps to avoid its losses. But how does this device work, which modifications exist, and how to choose the best equipment for your needs, we tell further.

How does a repeater for FPV and a relay station from BlueBird work?

A repeater for FPV is a compact and mobile device intended for the relaying of video signals and the control of drones. It receives the video signal from the drone through an FPV transmitter (receives video signals from the drone on the frequency of 5.8 GHz) and broadcasts it to a special device (screen, goggles, or monitor). The main task of the repeater is to ensure the stable transmission of data at a large distance (from 15 to 25 km) and in difficult conditions.

A relay station is a more powerful device intended for the reception of video signals and the management of drones. The station receives the signal from the drone’s FPV transmitter, amplifies it, and transmits it to the pilot’s receiving device, ensuring stable communication at a distance of up to 25 km. A significant advantage is the remote antennas, thanks to which the operator can control drones from a safe place (trench, vehicle, dugout, premises, and so on).

Modifications of the repeater for FPV.

When choosing equipment, take into account the following modifications:

Power. Greater power ensures a stable connection at large distances. By the way, our wireless repeater “Vishchun” 5.8 GHz makes it possible to increase the flight range to 25 km.

Automatic switching of channels. Makes it possible to avoid interference and ensure the stability of the connection. Thanks to our wireless repeater for the DJI Matrice 30 “Vishchun M30” + “Shakhrun”, one can remotely switch the channels of video communication.

External antennas. Antennas with high amplification for video and control can increase the flight range to 25 kilometers. They also ensure a stable signal in difficult conditions.

How to choose a repeater for FPV?

The correct choice of a repeater for FPV depends on several factors:

Transmission range. If you plan flights over large distances, you need equipment with high power. Whereas for amateur flights basic models of repeaters are used.

Type of terrain. For densely built-up or wooded territories, it is worth choosing models with a signal-amplification function. For military needs, modifications with protected channels and the automatic switching of frequencies are used. 

Modifications of antennas. On the type of antenna depend the stability and radius of action. So choose our collinear (for an omnidirectional signal), quadrifilar (for stability in conditions of interference), sector (for a directional signal), and patch antennas (for distant flights).

Conclusion. 

Overall, the choice of the correct FPV repeater guarantees stable video communication during flights at large distances and in difficult conditions. This is critically important on the battlefield, since the reliability of the signal can determine the success of reconnaissance operations and the precision of strikes.
