Video transmitters and receivers

A VTX (Video Transmitter) is a device used in FPV drones to transmit a video signal from the drone's camera to a ground receiver such as a monitor or FPV goggles. It is an important element of the FPV system, providing real-time transmission of the image during flight.
Main features of VTX for FPV:
Video Transmission – The VTX receives video from the FPV camera and transmits it to the pilot's receiver, allowing you to see in real time what the drone is seeing.
Frequencies and channels – video transmitters can operate on different frequencies (for example, 5.8 GHz) and support different channels, which allows you to avoid interference from other drones.
Adjustable transmission power - some VTXs allow you to change the signal power (for example, 25 mW, 200 mW or 2500 mW), which affects the range and quality of video communication.
Cooling and Protection – VTXs can have overheat protection systems and work with antennas for stable signal transmission over long distances.
Advantages of using VTX video transmitter in FPV drones:
Real-time: Thanks to VTX, the pilot receives video with minimal delay, which is especially important for high-speed flights and maneuvers.
Long transmission range: powerful models of video transmitters can transmit video over hundreds of meters or even kilometers.
Video quality: Modern VTXs support different video formats and allow you to adjust the quality according to the flight conditions.
