Video transmitter METELYK VTX 5.8GHZ 3W

The METELYK VTX 5.8GHZ 3W is an ultra-high-power analog video transmitter engineered for specialized long-range FPV operations within the standard 5.8GHz spectrum. Delivering 4 adjustable hardware power stages up to a massive 3000mW output ceiling, it guarantees exceptional signal propagation, dense obstacle penetration, and maximum link reliability. Housed inside a compact chassis, it features an integrated micro heatsink paired with an active cooling fan for dual-action thermal management. Outfitted with a wide 6V to 28V voltage tolerance, it accommodates a comprehensive 48-channel matrix and utilizes a dedicated physical hardware button interface for manual configuration.

Features

Extreme 3W Output Power: Outfitted with hardware-regulated power steps scaling up to a massive 3000mW maximum output, making it an ideal choice for specialized deep-range aircraft tracking.

Active Thermal Management: Combines a structural onboard micro heatsink with an active cooling fan to maximize airflow, ensure high operational efficiency, and prevent thermal locking during high-power deployments.

High-Density Integration: Built using large-scale integrated circuits to optimize electronic component density, delivering professional-grade impact resistance and reliability.

Micro Stack Compatibility: Minimalist layout features a standard 20x20mm mounting footprint, allowing ultra-high-power 3W deployment inside compact frames without adding significant bulk.

Dedicated Camera Power Rail: Features a clean, regulated 5V output line designed specifically to supply clean power to FPV camera modules or auxiliary electronics.

Operational Control Logic

Remote telemetry power adjustment is not supported on this module. Remote power state toggling via SmartAudio is locked out; output power scaling must be managed manually via the hardware button.

Frequency Channel Shifting: Short-press the physical setup button to cycle through internal channel profiles (1 through 8). The Blue CH1, CH2, and CH3 status LEDs will change configuration to verify the channel status.

Frequency Band Group Shifting: Press and hold the physical button for 2 seconds to enter the band selection mode, then short-press to cycle through the 6 available bands (A, B, E, F, R, L). The Red LED will flash a corresponding number of times to indicate the selected band.

Operational Power Scaling: Press and hold the physical button for 6 seconds to enter the power configuration menu, then short-press to cycle through the 4 available output stages (25mW, 1.6W, 2.5W, 3W). The Green LED will flash a corresponding number of times to indicate the active power stage.

Data Saving Protocol: After completing manual setup modifications, wait 8 seconds without touching the button. The VTX will automatically save parameters to internal flash memory and exit configuration mode.

Hardware Interface Pinout

5V OUT: Onboard Step-Down Regulatory Output for Camera Hardware

GND: Dedicated Camera Negative Ground

VIDEO: Analog Video Composite Feed Input from Flight Controller or Camera Lens

RX (SA): Telemetry Input Interface Port (SmartAudio/Serial Input)

GND: Primary Negative Power Ground Plane

VIN (6-28V): Primary Positive Power Input Link (2S–6S Battery Core)

Notes

Before use install the antenna. Running an ultra-high-power 3W VTX without a matching antenna will cause instant, catastrophic damage to the RF amplifier stage.

Fly with constant airflow and in a well-ventilated environment to prevent overheating. Operating extreme transmission profiles above standard levels may require specific operator licensing or local regulatory approval depending on your region.
