Foxeer FPV antennas are a favourite among drone racers and for good reason; they perform well, the quality is great and they don’t cost a fortune. The Echo 2 is a compact directional patch antenna intended for use on goggles. This is the latest version of the Echo, it has an extra 1db of gain over the original Echo antenna for even greater range. As a bonus the antenna even includes a 45-degree SMA adapter and wrench, so that you can mount the antenna at an appropriate angle to improve reception.
