Overview
iFlight Albatross V2.1 is a 5.8GHz FPV antenna featuring an upgraded rugged hexagonal design and a right-angle form for easier fixation. V2.1 uses upgraded welding technology to reduce weight while improving attachment security and consistency.
Key Features
- Hexagonal shape for enhanced durability; right-angle design for convenient fixation
- Ultrasonic welding technology for a lightweight, secure antenna attachment
- Improved consistency in antenna gain to support stable performance
- Polarization options and connectors covered by provided specs: RHCP SMA and LHCP RP-SMA
- Note for DJI Digital FPV use: RP-SMA LHCP is referenced; both sides should match polarization
Changelog
- July 17, 2025: Upgraded to version 2.1, using LDS technology; stated to provide more stable performance than V2.
