FPV video frequency

For drones, UAV video transmitters are like eyes to humans, relying on video transmitters for almost all its scouting functions. So, a good UAV video transmitter will help you get the most out of UAVs, and transmitters with different frequencies have different performance and prices, if you want to know, why not read this article?


Here is the content list:

1. What Is Frequency Of UAV Video Transmitter?

2. How Many Gears Is UAV Video Transmitter frequency?

3. Why Should We Pay Attention To Frequency Of UAV Video Transmitter?


What Is Frequency Of UAV Video Transmitter?

UAV video transmitter refers to a kind of radio equipment that the image will be conformed to certain standards of broadcasting audio and video signals, respectively, after on the fixed frequency modulation by frequency conversion to the provisions of the radio frequency (rf), and after power ambassador to put the power of the reach regulation of the feed to make the specified load antenna signal waveform conform to the requirements of the corresponding information standard UAV video transmitter frequency characteristics.

UAV video transmitter could have a significant potential impact on information acquisition and operations for military and civilian enterprises, as they offer advantages over traditional methods of manned helicopters in terms of cost, safety and convenience.


How Many Gears Is UAV Video Transmitter frequency?

As an important part of UAV system, UAV video transmitter will be improved with the development of information technology. Three frequencies of UAV video transmitter are usually available to meet the requirements of unmanned aerial vehicle systems for emergency relief, forest fire prevention, environmental monitoring, scientific research and testing and so on.

1. 840.5-845MHz

The 840.5-845mhzof UAV video transmitter can be used for up linking remote control link of UAV system, of which 841-845mhz can also be used for up linking remote control link and downlink telemetry link of hd video transmitter.

2. 1430-1446MHz

The 1430-1446mhz frequency band can be used for downlink telemetry and information transmission link of UAV video transmitter, among which the 1430-1434mhz frequency band shall give priority to ensuring the use of video transmission of police UAV and helicopters, and 1434-1442mhz frequency band can also be used for video transmission of police helicopters when necessary. hd video transmitter deployed in urban areas should use frequencies below 1442MHz.

3. 2402-2482MHz

The 2402-2482mhz frequency band can be used for downlink of UAV video transmitter, which shall not interfere with other legitimate radio services or seek radio interference protection.

If you are worried about relevant problems about laws and regulations, please feel assured that the use of frequency, radio station setting and radio transmitting equipment of our UAV video transmitter comply with relevant regulations of national radio management and unmanned aerial vehicle system management.


Why Should We Pay Attention To Frequency Of UAV Video Transmitter?

UAV video transmitter link system is an important part of UAV system. Its main task is to establish a two-way data transmission channel between ground and ground, which is used to complete the remote control, telemetry and task information transmission of UAV by ground control station. Unmanned aerial vehicle video transmitter enables remote operation of UAV and task equipment, and telemetry brings UAV state monitoring.

The transmission of task information, which is the key to the accomplishment of tasks of unmanned aerial vehicles, is directly related to the ability of discovering and recognizing targets through the wireless channel that brings down the UAV video transmitter.

1. Specific use

Unmanned aerial vehicles not only can be used not only for reconnaissance, but also as communication platforms. Compared with satellite communication platforms, UAV video transmitters have simple systems with high speed and low lag communication capabilities.

2. Important technical

In order to meet the requirements of software programmable network node, multi-beam antenna, low power consumption, no contact enhancement and stable link, new UAV video transmitter technologies must be developed.

3. Mixing degree of radio waves

Different frequencies are adopted by UAV video transmitter, while the higher the altitude is, the more appropriate frequency must be chosen to reduce losses even if high frequency is adopted.

In the long-distance communication relay using two-way directional antenna, if the frequency is different from that of air-ground link, there will be considerable technical problems. Since the limited capability of UAV video transmitter also limits the transmission distance and speed, there are still many problems that must be solved with respect to the control function of directional antenna in two-way transmission, as well as the flexibility with the relay plane that brings along and disconnects from the communication system.


In many cases, the diffraction or scattering capability that we pursue in choosing UAV video transmitter is not practical for the real-time transmission and control that we require. So the specific frequency is mainly depends on personal interest, but the only thing to pay attention to is the possibility of interference.
