LR1121 transmitters perform very well in long-range control systems, especially in the 433 and 868/915 MHz bands. The 1W output power is sufficient for most drone control tasks, especially when using directional antennas or repeaters. These transmitters are often used in ground stations or compact repeater systems. They provide stable signal and support multiple frequency bands.
