FlyFishRC Osprey 5.8GHz MMCX FPV Antenna (RHCP, 90mm)
The FlyFishRC Osprey is a highly efficient 5.8GHz FPV antenna built around a 4-leaf hybrid network design. This RHCP version features a direct MMCX connector and a 90mm stem length (104mm overall including the head and connector), making it an excellent choice for VTX systems that require a secure, snap-on MMCX connection. Weighing just 3.77g, it utilizes a resilient RG141 coaxial cable that holds its shape well to keep the antenna head positioned optimally above your frame. 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
- Optimized 90mm Length: Features a 90mm stem (104mm overall) that provides enough clearance for clean video transmission on smaller and mid-sized frames without adding excessive overhang.
- MMCX Integration: Connects directly to compatible video transmitters (such as select analog VTXs and digital air units) via a gold-plated MMCX connector for a secure, low-loss signal path.
- High Efficiency: Delivers a 2.82dBi gain and an exceptional 99% radiation efficiency for a highly stable video feed across the 5.6GHz to 6.0GHz band.
- Compact 4-Leaf Design: The antenna head remains highly compact, measuring just 14.1mm in diameter and 14mm in height, reducing aerodynamic drag.
- Crash Resistant: The transparent black polycarbonate casing is hermetically sealed to protect the internal elements from dirt, moisture, and impact damage.
