iFlight Albatross V2.1 5.8GHz Antenna

The iFlight Albatross V2.1 is a robust, high-efficiency 5.8GHz omnidirectional antenna designed for freestyle, racing, and long-range FPV builds. Encased in a durable polycarbonate shell, it provides excellent impact resistance while maintaining a clean, reliable video link across both analog and high-definition digital VTX ecosystems.

Key features

• High radiation efficiency and a low VSWR for consistent signal penetration behind obstacles.

• Tough polycarbonate radome protects the active internal elements from heavy crash impacts.

• Rigid but bendable coaxial cable allows you to angle the antenna exactly where it is needed without sagging mid-flight.

Specifications

• Frequency band: 5.8GHz (5000–6000MHz)

• Gain: 2.65dBi

• Axial ratio: ≤ 3

• VSWR: ≤ 1.5

• Lengths: 90mm, 130mm, 180mm

• Connectors: SMA, RP-SMA

• Polarisation: LHCP, RHCP

When selecting your variant, remember that LHCP is the standard for DJI and Walksnail digital systems, whereas RHCP is typically used for analog video. Longer 130mm and 180mm options are recommended for larger freestyle or cinelifter frames to ensure the antenna clears the battery pack and carbon fibre plates, preventing signal blanking as you fly away from yourself.
