Xtreem Cross-air Low band 5.2GHz 10dbi Long range fpv antenna (not 5.8 GHz)

Xtreeme Cross-Air V3 – High-Gain 5.2GHz Directional FPV Antenna

Built for pilots who demand maximum signal clarity and penetration, the Cross-Air V3 is a circularly polarized directional antenna optimized for the 5GHz band (5–5.5GHz). Its refined design delivers 10dBi gain with a wide 120° beamwidth, making it ideal for both long-range flights and technical proximity flying.

Key Features

• Frequency Range: 50–5.5GHz (covers Raceband, DJI, HDZero, and analog systems)

• VSWR <1.2  at band width about 200-250Mhz – Ensures minimal signal loss across the entire 5GHz spectrum 

• VSWR <1.5  at band width about 500Mhz

• 10dBi Gain – Focused signal strength for extended range and obstacle penetration 

• 120° Beamwidth – Balances directionality with usable coverage 

• RHCP/LHCP Options – Matches your system’s polarization (LHCP recommended for DJI/Walksnail) 

• Semi-Rigid Cable  – Holds position while allowing flexible mounting 

Why Choose the Cross-Air V3?

✔ Superior Multipath Rejection – Circular polarization reduces interference from reflections (e.g., trees, buildings) 
✔ Durable Construction – Reinforced casing withstands crashes and vibrations
✔ Universal Compatibility – Works with analog and digital systems (DJI, HDZero, Walksnail) 
✔ Lab-Tested Performance – Each unit verified for optimal VSWR and axial ratio
