GEPRC RAD VTX 5.8G 2.5W Video Receiver

The GEPRC RAD VTX 5.8G 2.5W is a high-power analog video transmitter engineered for specialized long-range FPV operations within the standard 5.8GHz spectrum. Delivering 6 adjustable power stages up to an extreme 2500mW output ceiling, it guarantees exceptional signal propagation, dense obstacle penetration, and maximum link reliability over long distances. Built with an innovative dual-layer PCB stack, it isolates the power regulation circuitry from the primary RF control core to maximize interference immunity and enhance thermal dissipation. Outfitted with a wide 7V to 36V voltage tolerance, an integrated microphone, and an active over-temperature protection loop, this VTX features three region-specific frequency tables and supports the standardized IRC Tramp protocol for effortless remote parameter tuning.

Features

High-Output Power Scaling: Outfitted with 6 adjustable power steps capable of stepping from stealth PIT mode up to a powerful 2500mW (2.5W) maximum output, delivering stable link retention over extreme flight boundaries.

Proven Long-Range Range: Field testing in optimal, interference-free maritime conditions demonstrates a maximum video transmission range extending up to approximately 10 kilometers.

Dual-PCB Isolated Architecture: Split-board structural design separates the high-draw power supply elements from the sensitive RF processing logic, minimizing video noise and optimizing passive cooling.

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 automatically throttling RF output stages if thermal safety thresholds are crossed.

Regional Frequency Flexibility: Pre-configured with three distinct channel mapping options (Universal 40CH, FCC 37CH, and EU 26CH layouts) to comply with local RF regulations and licensing authorities.

Single-Button Interface Logic: Features a simplified physical control interface pairing two setup buttons with 3 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 hardware.

Notes

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

When the over-temperature protection loop is triggered due to excessive heat, the VTX will automatically scale down output power to preserve component safety. Ensure constant airflow and a well-ventilated environment during operation, or install an auxiliary cooling fan if bench-testing 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 cause immediate and irreversible destruction to the VTX circuitry.
