📝 FPV Drone Control Dipole Antenna 433 MHz (390–640 MHz) with 15 cm Cable Aeronetix
The FPV drone control dipole antenna 433 MHz Aeronetix is designed for control and telemetry systems operating in the 433 MHz band and nearby SubGHz frequencies. The antenna has an omnidirectional radiation pattern and provides stable signal reception regardless of drone orientation. The center frequency without trimming is 435 MHz, and the operating range can be changed by trimming the antenna length. Used in ELRS, LRS, telemetry and other UAV control systems.

433 MHz antennas are commonly used in long-range UAV control systems because lower frequencies penetrate obstacles better and provide more stable communication. The dipole design provides uniform signal reception in all directions. Such antennas are typically installed directly on drone receivers or repeaters. The ability to adjust resonance frequency by trimming allows the antenna to be tuned for different frequency bands.
