Radiomaster RC RP4TD True Diversity ELRS 2.4ghz Receiver
Introducing the RadioMaster RP4TD, the pinnacle of ExpressLRS receiver technology, engineered for pilots who demand the ultimate in signal reliability and performance. This receiver features a true dual-channel diversity design, dual 100mW telemetry outputs, and dual TCXOs, making it a class leader for long-range flight, competitive racing, and any FPV drone application where a rock-solid link is non-negotiable.
The Ultimate in Signal Reliability: True Diversity
The RP4TD features two complete, independent receiver circuits, each with its own antenna and SX1281 RF chip. This “true diversity” system constantly analyzes the signal from both circuits and chooses the absolute best one, providing a level of redundancy and signal stability that is far superior to standard receivers. This technology virtually eliminates failsafes caused by signal blocking or antenna orientation.
Powerful Performance with Dual TCXO
This receiver is packed with professional-grade components. It includes two Temperature Compensated Crystal Oscillators (TCXO), ensuring that both receiver circuits remain perfectly on frequency even in extreme hot or cold conditions, preventing link issues caused by thermal drift. For a robust data link back to your radio, the RP4TD boasts two 100mW power amplifiers dedicated to telemetry, providing exceptional range for your vital flight information.
Ready for the Future: Gemini & mLRS
The RP4TD is a future-proof investment. It is fully compatible with all standard 2.4GHz ExpressLRS systems and is ready for the next generation of protocols, including ExpressLRS Gemini mode for dual-band redundancy. It is also now compatible with the mLRS open-source project, offering even more flexibility for advanced UAV and FPV drone builds.
