📝 Control Transmitter Aeronetix LR1121 TX 200–650 MHz 5W

The Aeronetix LR1121 TX 200–650 MHz 5W control transmitter is designed for long-range FPV drone and UAV control systems. The transmitter is built on the LR1121 modulator with an NPA1003 power amplifier that boosts the output signal up to 5W. It operates in a wide frequency range of 200–650 MHz, allowing use in various control systems and repeaters. Compatible with MilELRS and ExpressLRS firmware.

🫡 We are a team of veterans

From long-range control system experience, LR1121 transmitters provide very stable links at long distances, especially in frequencies below 700 MHz. The 5W output allows operation through repeaters or over very long distances with a proper antenna system. These transmitters are often used in ground stations or repeater systems. When configured correctly, the control link stability is very high.
