4 Blade Cloverleaf Antenna Drone Antenna FPV Antenna 4.9-6GHZ
Product Introduction
This Cloverleaf Antenna (also known as mushroom antenna) is specifically designed for 5.8GHz (4900–6000MHz) drone video transmission systems. It features Right-Hand Circular Polarization (RHCP) and an omnidirectional antenna structure, offering 360° horizontal coverage without dead zones and a vertical beamwidth of 8–73°. This design effectively suppresses multipath interference and signal fading, ensuring stable and clear video transmission even during high-speed and aggressive maneuvering. With 1.8–4dBi variable gain and approximately 80% efficiency, it is an ideal choice for FPV racing drones, competitive drones, and long-range video transmission.
Applications
- FPV racing drones and competitive drone video transmission systems
- 5.8GHz long-range telemetry and video downlink links
- Industrial drone anti-interference video transmission solutions
- Omnidirectional coverage mobile ground station receiving antennas
- Multirotor and fixed-wing drones for line-of-sight (LOS) and beyond-visual-line-of-sight (BVLOS) flights
