Video transmitter GEPRC RAD VTX 5.8G 1.6W

The GEPRC RAD VTX 5.8G 1.6W is a high-power analog video transmitter engineered for long-range FPV operations within the standard 5.8GHz spectrum. Delivering 5 adjustable power stages up to a high-penetration 1600mW output ceiling, it guarantees exceptional signal propagation and robust link stability. Featuring an innovative dual-layer PCB architecture, it physically separates the power regulation circuitry from the RF mainline to drastically suppress internal electronic noise and shield the video feed from interference. Outfitted with a wide 7V to 36V voltage tolerance, active temperature protection, and a built-in microphone, this VTX supports the standardized IRC Tramp protocol and includes three region-specific frequency tables for compliant global deployment.

Features

High-Output Power Scaling: Outfitted with 5 adjustable power steps capable of stepping from stealth PIT mode up to a powerful 1600mW (1.6W) maximum output, making it ideal for deep-range aircraft tracking.

Dual-Layer PCB Noise Shielding: Distinct dual-board stacked design isolates power conversion from signal processing layers, optimizing thermal dissipation while eliminating voltage ripple interference.

IRC Tramp Telemetry Interface: Seamlessly integrates with standard IRC Tramp protocol fields, allowing pilots to modify video channels, bands, and power steps directly through the Betaflight OSD.

High-Acoustic Onboard Microphone: Features a built-in miniature microphone transmitting real-time motor and environmental audio telemetry straight to the pilot's audio receiver.

Intelligent Over-Heat Safety: Built-in temperature control monitoring actively safeguards internal processing circuits by throttling RF output stages if thermal safety thresholds are crossed.

Regional Frequency Flexibility: Pre-configured with three distinct channel mapping options (Universal, FCC, and EU layouts) to comply with local RF regulations and licensing authorities.

Dual-Button Interface Logic: Simplified hardware interface using two tactile setup buttons paired with three bright LED diagnostic indicators for instantaneous, tool-free field adjustments.

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

Notes

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

Fly with constant airflow and in a well-ventilated environment to prevent overheating. Install an additional cooling fan if operating in confined spaces.

The 5V output is designed strictly for powering the FPV camera or small auxiliary fans. Never connect the main power supply or battery mainline to this 5V output line, as it will destroy the VTX circuitry.
