5.8Ghz 9.3dbi RHCP Helical Antenna (SMA)
A new development for FPV antennas. It's a 2.75 turns helix, the turns are more closely spaced than a conventional helix, and it uses a parasitic disk to achieve higher gain (9.3dBi) and better axial ratio compared to a regular helix.
The result is a very compact moderately directional antenna with very good efficiency, and same gain as a 4 turns conventional helix. The total length is less than half that of a comparable 4 turns helix, which is slightly more than a linear patch antenna.
