iFlight ExpressLRS True Diversity Receiver (160mm Mini Antenna)

The iFlight ELRS 2.4GHz True Diversity Receiver is built for long-range and demanding freestyle FPV flights where control link reliability is critical. Unlike standard receivers that merely switch between antennas, this true diversity unit employs two independent RF chips to actively listen to and combine signals from both 160mm mini antennas simultaneously. This architecture significantly reduces dead zones, polarization loss, and multipathing interference in challenging environments.

Key features

• True diversity architecture with dual independent RF chains for maximum link stability.
• Integrated Wi-Fi module allows for convenient over-the-air (OTA) ExpressLRS firmware flashing and configuration.
• Includes two 160mm mini dipole antennas, providing enough wire length to clear large carbon fibre frames or cinelifter payloads.
• Standard UART wiring pads (5V, Ground, TX, RX) for simple integration with any modern flight controller.

To take full advantage of the dual-antenna diversity system, ensure the two included antennas are mounted at a 90-degree angle to one another (orthogonal) on your frame, keeping the active elements well clear of carbon fibre plates and thick battery leads. Gemini mode needs a transmitter module that supports Gemini.
