Product Overview
The RFVTX584940 is a high-performance full-band analog video transmitter built for professional FPV ultra-long-range flight and industrial UAV operations. Different from conventional single 5.8G band VTXs, it achieves 4.9GHz-5.8GHz ultra-wide frequency band coverage with 56 independent working channels, greatly expanding frequency point options. It can utilize the excellent diffraction and penetration capability of the low frequency band to cope with complex obstructed environments, and flexibly switch frequencies to avoid co-channel interference, maintaining stable and smooth video transmission even in complex electromagnetic environments such as urban areas and multi-device scenarios.
It supports 5 freely adjustable transmit power levels, covering all scenarios from 25mW to 4000mW (4W). The maximum 4W high-power output significantly improves transmission distance and signal penetration, easily coping with extreme scenarios such as ultra-long-range flight and mountain/forest obstruction. It supports direct wide-voltage power supply from 2S to 6S LiPo batteries, compatible with the native power systems of most FPV racing drones, fixed-wing UAVs and small-to-medium industrial operation drones, with easy installation and strong adaptability. Paired with a reinforced heat dissipation structure and highly reliable circuit design, it can operate stably at full power for a long time, making it a high-performance choice for professional pilots and industrial scenario VTX upgrades.

Core Features & Benefits
1. 4.9G-5.8G Full-Band Coverage with 56 Channels for Superior Anti-Interference
Breaking through the limitation of conventional single 5.8G band, it achieves ultra-wide frequency coverage from 4.9GHz to 5.8GHz. The 4.9G low frequency band has longer wavelength and stronger diffraction and penetration capability, with less signal attenuation and more stable picture in scenarios such as urban buildings, forest obstruction and mountain terrain. 56 independent working channels provide massive frequency options, which can be flexibly switched according to the on-site electromagnetic environment to effectively avoid co-channel interference. It supports multi-drone simultaneous operation with different frequencies, greatly improving VTX reliability in complex environments.
2. 5 Precision-Adjustable Power Levels with 4W Max Long-Range Performance
It supports free switching of 5 transmit power levels: 25mW, 400mW, 1000mW, 2000mW and 4000mW (4W):
- The 25mW low-power mode is suitable for indoor practice and close-range test flight, with low electromagnetic interference and lower power consumption;
- Medium power levels meet daily freestyle flight and ordinary venue long-range flight, balancing battery life and transmission distance;
- The maximum 4000mW (4W) high-power mode greatly improves signal transmission distance and penetration capability, easily coping with extreme scenarios such as ultra-long-range flight and complex terrain obstruction, ensuring stable and uninterrupted video.
3. Wide 2-6S Direct Power Supply for Broad Drone Compatibility
It supports a wide input range from 2S to 6S LiPo batteries directly, without additional step-down or voltage regulator modules. It is perfectly compatible with various aircraft including mainstream 3-6S racing drones, long-range drones, fixed-wing UAVs and small-to-medium industrial inspection drones, greatly reducing the installation threshold, and is convenient for both new drone assembly and old equipment upgrades.
4. Reinforced Thermal Design for Stable Long-Time Full-Power Operation
Specially optimized heat dissipation design for high-power wide-band operation scenarios, adopting high thermal conductivity heat dissipation structure and optimized high-current circuit layout to quickly dissipate heat generated during full-power operation, effectively control the overall temperature rise, and avoid power attenuation, signal jump and even equipment damage caused by high temperature. It ensures stable output during long full-throttle long-range flight and continuous operation, and improves equipment service life and reliability.
5. Standard AV Interface for Plug-and-Play Easy Installation
Adopting industry-standard analog AV video input interface, it is fully compatible with various analog FPV cameras and flight control OSD character overlay systems with stable video signal transmission. The compact and lightweight structure fits mainstream frame mounting positions, with simple wiring and no complicated debugging required, enabling quick setup and use.
