IFlight True Diversity ELRS 868/915 MHz RX with 2x 70mm Antennas

Introduction

The iFlight ELRS True Diversity Receiver is a high-performance FPV receiver developed in close collaboration with the ExpressLRS team. This true diversity receiver utilizes dual antennas with shielding to combat interference, expand signal reception, and deliver a more stable connection compared to single-antenna systems. It's ideal for FPV pilots demanding reliability for long-range flights, aerial photography, and intense freestyle maneuvers.

Key Advantages

• True Diversity and Gemini mode compatibility for enhanced reception.
• Integrated shielding protects electronics and boosts interference resistance.
• Temperature Compensated Crystal Oscillator (TCXO) ensures high-frequency stability and reduces packet loss.
• High telemetry transmission power (up to 500mW at 868/915 MHz) for stronger signals and fewer telemetry losses.
• Dual-band support for 868 MHz (EU) and 915 MHz (FCC) frequencies.
• Compact and lightweight design at only 4.2g.
• Designed for reliable long-distance FPV operations.
• Optimized for use with iFlight transmitters for maximum performance.

FAQ

What makes the iFlight True Diversity ELRS Receiver ideal for long-range FPV flights?

The iFlight ELRS True Diversity Receiver uses two antennas with shielding and a temperature-compensated crystal oscillator (TCXO) to ensure a stable, interference-free signal over long distances. Its high telemetry power output also helps maintain a strong connection.

Can I use this iFlight ELRS receiver with any FPV transmitter?

For maximum performance and compatibility, it's recommended to use iFlight ELRS receivers with iFlight transmitters. If you want to use the Gemini mode, your transmitter must also support this feature. It uses the CRSF protocol.

What are the supported frequency bands for the iFlight True Diversity ELRS Receiver?

This receiver supports dual-band operation, offering flexibility with 868MHz frequencies for the EU region and 915MHz frequencies for the FCC region.

How does the True Diversity system improve signal reception?

The True Diversity system uses two separate antennas and receivers to pick up signals. The system intelligently selects the best signal at any given moment, significantly reducing signal loss and improving overall connection stability compared to single-antenna setups.
