iFlight Albatross 150mm V2 5.8Ghz Antenna RHCP SMA

iFlight Albatross 150mm V2 5.8GHz Antenna – Durable RHCP FPV Solution

The iFlight Albatross 150mm V2 5.8GHz Antenna is engineered for pilots who require stable signal transmission across analog and digital FPV platforms. Designed with upgraded structural durability, this V2 model improves gain consistency, radiation efficiency, and mechanical strength compared to standard stock antennas.

Operating across the 5.3GHz–6GHz frequency range, this antenna supports common 5.8GHz FPV systems used in racing drones, freestyle quadcopters, and long-range builds. The RHCP polarization ensures proper circular signal matching with compatible transmitters and goggles, helping reduce multipath interference and signal dropouts.

iFlight Albatross Antenna Mechanical Design

The V2 version introduces a reinforced hexagonal outer housing that improves durability under crash conditions. Ultrasonic welding technology secures the antenna core, reducing internal movement and preserving signal integrity. The right-angle design simplifies frame mounting and keeps the antenna positioned for optimal radiation pattern distribution.

Weighing approximately 11.5 grams and featuring a 150mm RG141 cable, the antenna balances flexibility with strength. The cable construction enhances shielding performance and maintains signal stability during aggressive flight maneuvers.

iFlight Albatross Antenna RF Performance

The antenna achieves an average gain of approximately 2.4dBi within the operating band. With controlled VSWR values and radiation efficiency averaging above 80%, signal transmission remains efficient and consistent. Cross polarization suppression of around -25dB further minimizes interference from opposite polarization signals.

For pilots using advanced digital video systems, pairing compatible antennas ensures improved video clarity. For example, digital transmission users may explore systems like the Caddx Walksnail Avatar GT KIT for enhanced output performance. Analog pilots seeking high-gain alternatives can also consider the FPV Drone Mushroom Antenna depending on frame layout and mounting preferences.

Compatibility & Polarization Matching

This RHCP SMA version is designed for systems requiring right-hand circular polarization. Proper polarization matching between transmitter and receiver is essential to maintain optimal link quality. When polarization mismatches occur, signal strength and clarity can degrade significantly.
