Mjölnir-Pro is built for the DJI FPV HD system specifically in mind. Hybrid polarized antenna technology is used to improve the bit rate and remote control distance of the HD system. This upgraded version optimizes the portability and storage problems of the previous version of Mjölnir. 

They have four 8.5dBi circularly polarized directional antennas and two circularly polarized omnidirectional antennas for air units. If you use Caddx Vista Air Units, they will work well. The operating frequency of the antenna is 5660-5914 mHz. Please choose the appropriate working channel according to the interference condition in the flight field.

The Mjölnir-Pro continues to use hybrid polarized antenna technology, achieving a huge breakthrough in portability without sacrificing performance by optimizing the antenna array and polarized hybrid mode.

A radio wave with circular polarization will change its polarization direction after reflection. In the environment with obstacles, the mixed-polarization antenna combination can always receive multi-path signals in the shortest time. They complement each other and take full advantage of all the reflection in a real FPV environment. We often shuttle between buildings. Maple wireless Mjölnir-Pro Antenna series can maximize the DJI FPV high-definition image transmission system advantages, improve the code rate and flight experience.

Couple of bucks more than crystal setup

Sleek, small form factor. Direct and reflected reception. Works well with Vista, but engineered for air unit. Hard to find, but needed had them for the win!

Maple wireless DJI

They have been making antennas for over 100 years, maybe we should trust them.
