Product details
The Foxeer Echo 2 is a compact 5.8GHz patch antenna for goggles and ground stations, giving a strong directional signal for long-range analog FPV. It keeps the size of the first-generation Echo but moves to a double-layer board for better performance, and comes in RHCP or LHCP to match the antenna on your aircraft.

98% radiation efficiency and VSWR below 1.15 at centre frequency

Compact 34 x 34 x 61 mm body

Polarisation: RHCP or LHCP (choose variant)

The SMA plug fits goggles and receiver modules with SMA ports, such as the Skyzone Cobra series; goggles with RP-SMA ports need an adapter. Run it on one diversity port with an omni antenna on the other so you keep signal when the quad is beside or behind you, and match its polarisation to the antenna on your aircraft.
