Product Overview
The RFVTX3340 is a high-power analog video transmitter (AV VTX) built for long-distance FPV flight and industrial UAV inspection, operating on the 3.3GHz frequency band. Adopting a dedicated low-frequency 3.3G solution, it delivers stronger diffraction and penetration capability than mainstream 5.8G VTXs, maintaining stable and smooth video transmission even in complex terrains with tree cover, building obstructions, and mountainous areas, greatly improving the reliability of long-range flight and outdoor operations.
It supports 16 independent working channels for free switching, with a maximum transmit power of 4000mW (4W). It is also equipped with a PIT low-power mode (2mW), meeting the different needs of close-range ground tuning and long-distance air flight. Supporting wide-voltage 2-6S LiPo battery input, it is compatible with the power systems of most FPV racing drones, fixed-wing UAVs, and industrial drones. With easy installation and strong compatibility, it is a cost-effective choice for professional pilots’ long-range flight and industrial UAV VTX upgrades.

Core Features & Benefits
1. 3.3G Dedicated Low-Frequency Band for Strong Penetration & Long Range
Operating on the dedicated 3.3GHz VTX frequency band, it has a longer wavelength than conventional 5.8G VTXs, delivering significantly better diffraction and penetration capability. It maintains stable video transmission even in complex terrains with tree cover, building obstructions and hilly areas, effectively reducing video snow, frame loss and disconnection issues, and greatly improving transmission distance and operation reliability for long-range flight.
2. 4W High Power Output with Flexible PIT Mode Switching
It supports a maximum transmit power of 4000mW (4W) for longer signal transmission distance and stronger penetration, fully meeting the video transmission needs of ultra-long-range FPV flight and long-distance industrial inspection. The PIT low-power mode (2mW) is available for ground tuning and close-range test flight, reducing electromagnetic interference and unnecessary power consumption for more flexible usage scenarios.
3. 16 Selectable Channels for Multi-Drone Anti-Interference
Built-in 16 independent working channels can be flexibly switched according to the on-site electromagnetic environment to effectively avoid co-channel interference. It supports multi-drone simultaneous operation and formation flight, adapting to scenarios such as FPV competitions, group aerial photography, and multi-drone industrial inspection, ensuring signal stability when multiple devices work in parallel.
4. 2-6S Wide-Voltage Power Supply for Wide Drone Compatibility
It supports a wide input range from 2S to 6S LiPo batteries, compatible with the native power systems of most FPV racing drones, fixed-wing UAVs and industrial drones. No additional step-down/step-up modules are required, and it works immediately after wiring, making it convenient and worry-free for both new drone assembly and old equipment upgrades.
5. Optimized Thermal Design for Stable Long-Time Operation
Adopting an efficient heat dissipation structure and optimized circuit layout, it quickly dissipates the heat generated during high-power operation, effectively controls operating temperature rise, and avoids problems such as high-temperature frequency reduction, power attenuation and signal instability. It ensures stability and equipment durability during long-time full-load flight operations.
6. Standard Interface Design for Easy Installation & Strong Compatibility
Adopting industry-standard analog AV video input interface, it is perfectly compatible with various analog cameras and flight control OSD systems, plug-and-play without complicated debugging. The compact and lightweight design fits mainstream frame mounting positions without adding excessive weight burden to the aircraft.
