Best Antennas for FPV Drones
Enhancing the range and penetration of FPV drone systems is a common pursuit among enthusiasts. Selecting the appropriate antenna can significantly boost signal strength and reliability. Here are some top options:
Tips for Selection:
Ensure compatibility with your drone’s air unit and frequency. Most FPV systems use 5.8 GHz antennas, but it's crucial to match the antenna frequency to your FPV equipment. For more info please see: LHCP/RCHP Antenna Guide and Ultimate Guide to FPV Drone Antennas
Consider the physical size and mounting constraints. The antenna should fit well within your drone's design without adding excessive weight or drag.
Omni-directional antennas are better for general use, while directional ones excel in long-range flights. Omni-directional antennas provide wide coverage, making them ideal for general FPV flying, whereas directional antennas focus the signal in a specific direction, suitable for long-distance flights.
Higher gain often means longer range but a narrower signal beam. High-gain antennas can extend your range but require more precise alignment due to their narrower beamwidth.
Specific FPV Antennas
