Product Overview
The RFVTX6420 is a 6.4GHz analog video transmitter (AV VTX) built for professional FPV flight and industrial UAV operations. Addressing the common pain point of severe co-channel interference in the crowded 5.8GHz band, it adopts a dedicated clean 6.4GHz frequency band to greatly reduce co-channel interference risk. Even in complex electromagnetic environments such as urban areas and multi-device scenarios, it maintains clear and stable video transmission with clean footage and minimal noise, significantly improving transmission reliability.
It is equipped with two transmit power levels: PIT low-power mode and 2000mW (2W) high-power mode, covering both close-range ground tuning and medium-long range air flight. Built-in 16 independent working channels allow flexible frequency switching to further avoid interference. It supports direct wide-voltage power supply from 2S to 6S LiPo batteries, perfectly compatible with mainstream FPV racing drones, fixed-wing UAVs and small-to-medium industrial operation drones. Paired with optimized heat dissipation structure and reliable circuit design, it delivers stable performance during long-time full-load operation, making it a cost-effective VTX solution for professional flight and industrial operations in complex electromagnetic environments.

Core Features & Benefits
1. Dedicated Clean 6.4G Band for Superior Anti-Interference Performance
Adopting the dedicated 6.4GHz VTX frequency band, it has far lower co-channel interference probability than the crowded 5.8GHz band with a cleaner electromagnetic environment. Even in complex environments such as urban buildings, multi-drone scenarios and dense electronic equipment surroundings, it outputs clean and stable video footage, effectively reducing snow noise, disconnection and frame freezing issues, and significantly improving VTX reliability for flight and operation.
2. Dual Power Levels for Full Scenario Adaptation
Equipped with two transmit power levels: PIT low-power mode and 2000mW (2W) high-power mode:
- PIT mode is suitable for ground tuning and close-range test flight, with low radiation and low power consumption to reduce surrounding electromagnetic interference;
- The 2000mW (2W) high-power mode delivers sufficient transmission distance and penetration capability, easily coping with medium-long range flight and lightly obstructed terrain to ensure stable video return.
3. 16 Independent Channels for Flexible Interference Avoidance
Built-in 16 independent frequency points can be flexibly switched according to the on-site electromagnetic environment to further avoid surrounding signal interference. It supports multi-drone simultaneous operation with different frequencies, suitable for team flight, industrial multi-drone inspection and competition events to meet diverse usage demands.
4. 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 FPV racing 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.
5. Optimized Thermal Design for Stable Long-Time Full-Power Operation
Optimized heat dissipation structure and circuit layout for high-power operation scenarios quickly dissipate operating heat, effectively control overall temperature rise, and avoid power attenuation and signal instability caused by high temperature. It ensures stable output during long full-throttle flight and continuous operation, and improves equipment durability and reliability.
6. 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.
