Sequre 2.4G Dual RX True Diversity ExpressLRS ELRS Receiver with PA+LNA – Dual Antenna

This 2.4GHz ELRS receiver incorporates two SX1281 RF chips, essentially it is like having two receivers in one. With true diversity technology and dual antennas, it ensures robust signal reception even in challenging environments.

The receiver is compatible for ELRS Gemini Mode. Using Gemini Mode the radio broadcasts two separate transmit chains on slightly difference frequencies, simultaneously, to send control information to a Gemini compatible receiver twice. This helps to ensure even greater signal stability, as you effectively have two RC links. If one signal gets blocked then there’s a chance the other will still be received.

It features dual PA (Power Amplifier) & LNA (Low-Noise Amplifier) to further boast signal reception and telemetry range. The Rx can transmit at a power of 100mW.

It offers high-speed data transmission, meeting the low-latency requirements of FPV racing drone pilots. The receiver supports ELRS’s maximum F1000Hz refresh rate.

It also contains a “temperature-compensated crystal oscillator” (TCXO), – a thermally compensated crystal. This ensures a stable oscillator frequency and stable RC transmission even with larger temperature fluctuations.

Aside from the quality components used in this RX, what really makes it stand out from other ELRS receivers is the flexibility offered when it comes to connection methods. Like most other ELRS receivers it has solder pads, but it also has a socket connection (SH1.0-4P). 

The receivers measures just 23mm by 13mm and weighs a mere 1.5 grams without the antenna. It is supplied with two T-antennas, a choice of lengths available: Choose between 80mm and 220mm. Installing the antennas in different positions and orientations is recommended to take advantage of the diversity antenna system.
