Foxeer 4.9G Echo 2 Patch Antenna

Foxeer 4.9G Echo 2 is a high-performance directional circular polarized patch antenna, engineered specifically for the 4.9 GHz frequency band. Featuring a high gain profile, this antenna is an ideal solution for ground stations or FPV goggles to maximize range during long-range flights and specialized radio operations.

The Echo 2 design is optimized to deliver a focused and powerful radiation beam, significantly increasing video signal penetration and range compared to standard omnidirectional antennas. The shell is molded from premium, UV-stable, and weather-resistant materials, ensuring long-lasting field durability. With an exceptional axial ratio and low voltage standing wave ratio (VSWR), it guarantees crisp video reception with minimal interference over extended distances.

This antenna is most commonly deployed on the receiver side (VRX) in combination with an omnidirectional antenna (like the Foxeer Lollipop) to build an efficient diversity setup.
