Product overview
The iFlight Albatross V2.1 5.8GHz 180mm Antenna RHCP RP-SMA operates across 5.3GHz-6GHz with right-hand circular polarization and an RP-SMA interface. Its construction combines LDS technology with ultrasonic welding for a lightweight, secure antenna attachment. A hexagonal shape enhances durability, while the right-angle design makes fixation convenient. The antenna uses RG141 cable and weighs 12.2±0.5g. Introduced on Dec. 25, 2025, the V2.1 upgrade provides more stable performance than V2. An FPV frame is not included.
The RHCP configuration has an average gain of 2.9dBi, an average VSWR of 1.48 and average radiation efficiency of 66.51%. Maximum gain is 3.02dBi at 5500MHz, with minimum gain of 2.85dBi at 5700MHz. Maximum VSWR is 1.76 at 6000MHz, and minimum VSWR is 1.20 at 5300MHz. Radiation efficiency reaches a maximum of 68.77% at 5700MHz and a minimum of 65.17% at 5300MHz. Cross polarization suppression is -25dB, and the axial ratio is ≤3.
