4 Blade Cloverleaf Antenna Drone Antenna FPV Antenna 1.28-1.45GHZ
Product Introduction
This Cloverleaf Antenna (also known as mushroom antenna) is specifically designed for 1.4GHz (1280–1450MHz) drone video transmission systems. It adopts a classic omnidirectional antenna structure, offering 360° horizontal coverage and a wide vertical beamwidth of 19–81°, ensuring stable signal reception and transmission regardless of the aircraft's attitude. With 2dBi gain and approximately 78% efficiency, it is an ideal choice for FPV aerial photography, long-range video transmission, and industrial drone applications.
Applications
- FPV racing drones and aerial photography drone video transmission systems
- 1.4GHz long-range telemetry and remote control links
- Industrial drone anti-interference video transmission solutions
- Omnidirectional coverage mobile ground station receiving antennas
