RadioMaster XR4 Dual Antenna Receiver – Long Range ExpressLRS FPV & RC Drone RX

RadioMaster XR4 Dual Antenna Receiver – Long Range ExpressLRS FPV & RC Drone RX

The RadioMaster XR4 Dual Antenna Receiver is the ultimate choice for pilots who prioritize reliability above all else. Built on the revolutionary ExpressLRS protocol, this receiver features a true diversity design, meaning it actively monitors and switches between two antennas to provide the cleanest possible signal at all times. Whether you are navigating dense forests, flying around concrete structures, or pushing the limits of your long-range mission, the XR4 keeps your control link locked in tight.

The Power of True Diversity

Why settle for one antenna when you can have two? The dual-antenna "diversity" setup of the RadioMaster XR4 solves the biggest problem in FPV: signal fading caused by orientation changes or obstacles. By constantly evaluating the signal from both antennas, the XR4 ensures you always have the strongest link possible, virtually eliminating the "brown-outs" that can ruin a perfect flight. It is the peace of mind that professional pilots rely on.

Engineered for Professionals

RadioMaster has built the XR4 with the same high standards they use for their world-famous radios. It features a robust, compact PCB that fits into almost any FPV frame, alongside industry-standard mounting points. Because it supports the high-speed ExpressLRS protocol, it offers the lowest latency on the market, ensuring that your drone reacts to your inputs with near-instantaneous speed.

Key Features

• True Diversity Design: Dual antennas provide superior signal coverage and resilience against fading and interference.

• ExpressLRS Protocol: Industry-leading range, low latency, and high refresh rates for a "locked-in" flight feel.

• Rock-Solid Reliability: Specifically engineered to provide a stable link in challenging environments where single-antenna receivers might fail.

• Compact & Easy to Mount: Designed to fit easily into modern FPV drone frames while providing plenty of room for your other electronics.

• Professional Build Quality: Built by RadioMaster, ensuring top-tier consistency and durability.

Why Pilots Choose the RadioMaster XR4

Pilots who fly expensive, high-performance drones choose the RadioMaster XR4 because they want to protect their investment. It is the gold standard for "no-compromise" builds. If you are flying cinematic rigs, high-stakes race quads, or industrial long-range drones, the XR4 is the receiver that provides the most reliable radio link money can buy.
