Note: Please assemble the antenna before powering on. Otherwise, the PA chip in the SuperG Nano Transmitter will be damaged permanently.

The following is the comparison information of the 3 products SuperG Nano Transmitter, ELRS Nano TX Module and ELRS Micro TX Module. It shows the advancing updates and specifications more than ever.

Know More About Diversity&Gemini

• Antenna Diversitymode, two antennas. Switch the two antennas regularly to read the RSSI value of the signal and determine which antenna to use to receive data.
• True Diversity mode, where both antennas receive data at the same frequency, and the antenna that receives the correct data first is used.
• Gemini mode, where two antennas simultaneously receive telemetry data with a frequency difference of 40MHz. They also transmit data simultaneously but at different frequencies. This means that you can receive the same data packets on different frequencies and antennas. This mode provides stable flight even in complex radio environments.

Among them, Gemini is the most advanced function yet of ExpressLRS – Gemini mode currently! It owns the most stable mode for receiving signals and offers higher resistance to interference and stability, making it suitable for various applications.

SuperG Nano Transmitter features Gemini mode. In atesting video by developer Jye Smith, it is shown that with a refresh rate of 1000Hz, the LQ value fluctuates between 90-100 when the true diversity receiver is in operation. However, after switching to Gemini mode, the LQ value stabilizes at 99-100. This demonstrates that ELRS goes to great lengths to ensure link stability.

Combination with Diversity RX

Gemini mode is built upon the hardware foundation of true diversity receivers and requires a dual RF output high-frequency module. When used with Super series products, the advantages of Gemini mode can be fully utilized. And Theeffectsofusingthetransmitter andreceiverinvariousmodesareasfollows:
