4 Blade Cloverleaf Antenna Drone Antenna FPV Antenna 5700-5850MHZ
Product Introduction
This Cloverleaf Antenna (also known as mushroom antenna) is specifically designed for 5.8GHz (5700–5850MHz) 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 wide vertical beamwidth of 78–83°. This design effectively suppresses multipath interference and signal fading, ensuring stable and clear video transmission across various flight attitudes. With 2dBi gain and approximately 76% efficiency, it is an ideal choice for FPV racing drones, aerial photography drones, and industrial video transmission.
Applications
- FPV racing drones and aerial photography 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
