TrueRC Sniper II 5.8 LHCP RP-SMA Antenna for Avatar Goggles X

The TrueRC Sniper II 5.8 is a compact high-gain directional antenna for 5.8 GHz FPV video, built to push range further from the goggles. This version is LHCP with an RP-SMA connector, the configuration for Walksnail Avatar Goggles X, and it suits long-range, mountain and fixed-wing pilots who fly out in front of them rather than all around.

Key features

• 13.5 dBic gain from a body only 52 × 52 × 37 mm, small enough to mount on goggles without a separate ground station.
• 5.3–6.5 GHz coverage spans the standard 5.8 GHz channels plus the extended low and high bands.
• Useful beam: 80° where reception at least matches an omni, and a 45° core (-3 dB) where you keep at least 70% of maximum range, horizontally and vertically.
• 98% radiation efficiency, so very little signal is lost in the antenna itself.
• LHCP polarisation: pair it with LHCP antennas on the aircraft.

Fit it on one goggle port and keep an omni on the other: the Sniper II carries range ahead, while the omni holds the link when the aircraft passes overhead or behind you. Keep your head turned towards the aircraft to stay inside the beam.
