Unlock Crisp, Long-Range Video: The Ultimate 4.5-6.5GHz High-Gain Antenna for FPV & Telemetry

Tired of video breakup and weak control signals at the edge of your range? This 4.5-6.5GHz 21dBi Broadband Patch Antenna is engineered to deliver exceptional signal strength and clarity for your most demanding flights. Covering the critical 4.5-6.5GHz spectrum (including popular 5.3GHz, 5.8GHz FPV, and 5.9GHz bands), its super flat profile and high 90% efficiency provide a massive upgrade over standard antennas, ensuring robust video transmission and reliable control for long-range FPV, drone mapping, and professional UAV operations.

Why Pilots Choose This High-Performance Antenna:

Maximize Your Video Range: With a peak gain of 21dBi, this antenna focuses your signal into a powerful beam, dramatically extending your FPV video and control link distance while reducing interference.
Broadband Versatility: Seamlessly covers 4.5-6.5GHz, making it compatible with a wide range of systems including 5.8GHz analog/digital FPV, 5.3GHz HD systems, CPE devices, and telemetry links—all with one future-proof antenna.
Engineered for Efficiency: Achieves ≥90% radiation efficiency, meaning almost all input power is converted into effective signal strength, not lost as heat, giving you the maximum performance per watt.
Stable, Focused Signal Pattern: Features a consistent ~12° Half-Power Beamwidth and a strong 14dB Front-to-Back Ratio, providing excellent directional stability and rejection of signals from the rear for a cleaner link.
Rugged & Low-Profile Design: Built on a sturdy 200x200x7mm fiberglass substrate, it’s both lightweight (198g) and durable. Its ultra-flat form factor minimizes drag and is perfect for ground station tripods or vehicle mounting.
