4 Blade Cloverleaf Antenna Drone Antenna FPV Antenna 2.4GHZ
Product Introduction
This Cloverleaf Antenna (also known as mushroom antenna) is specifically designed for 2.4GHz (2400–2500MHz) drone video transmission and remote control systems. It features Circular Polarization (CP) and an omnidirectional antenna structure, offering 360° horizontal coverage without dead zones and a wide vertical beamwidth of 81–92°. This design effectively suppresses multipath interference, ensuring stable and clear signal transmission regardless of the aircraft's attitude. With 2dBi gain and approximately 82% efficiency, it is an ideal choice for FPV racing drones, aerial photography drones, and industrial long-range video transmission.
Applications
- FPV racing drones and aerial photography drone video transmission systems
- 2.4GHz long-range telemetry and remote control links (e.g., OpenTX, ELRS, etc.)
- Industrial drone anti-interference video transmission solutions
- Omnidirectional coverage mobile ground station receiving antennas
- Multirotor and fixed-wing drones for line-of-sight and mild beyond-visual-line-of-sight (BVLOS) flights
