FlyFishRC Osprey 5.8GHz U.FL FPV Antenna (140mm)
The FlyFishRC Osprey is a highly efficient 5.8GHz FPV antenna built around a 4-leaf hybrid network design, available in both RHCP and LHCP configurations to match your specific video system. Featuring a direct U.FL (IPEX 1) connector and a 140mm stem length (154mm overall including the head and connector), it is perfectly suited for routing out of your frame to clear the battery and carbon fiber for an unobstructed signal. Weighing just 3.56g, it utilizes an RG1.13 coaxial cable wrapped in a durable protection tube to prevent cuts from sharp frame edges or propeller strikes. The compact antenna head is enclosed in an impact-resistant, hermetically sealed polycarbonate casing, ensuring its 2.82dBi gain and 99% radiation efficiency remain perfectly intact even after hard crashes.
Key Features
- Variable Polarization: Available in both RHCP and LHCP to ensure perfect compatibility with your analog or digital video receivers.
- Optimized Length: Features a 140mm stem (154mm overall) that allows the antenna head to easily clear the drone’s frame and battery, drastically reducing signal blocking.
