The new Immersion Circular Polarized patch antenna is the latest in the Groundbreaking SpiroNET line. The new CP Patch antenna is lightweight, Headset-mountable, and has unbelievable range.
Custom designed for the FPV market, it pushes the limits of range on 5.8Ghz, with 13dBi gain multi-km flights are possible even on CE-legal 25mW systems. For 600mW systems, it’s time to start worrying about the range of the control link, since with a combination of this antenna, and a spiroNET omni, the video range can greatly exceed the control range of most 2.4GHz radios.
Precision manufactured with very tight tolerances and 100% tested on a professional antenna tester (Rhode & Schwartz) to ensure maximum range and performance, No expense was spared. Its Light enough to be mounted directly onto an LCD headset, or directly onto the front of one of our Uno, or Duo receivers.
If your starting to feel limitations of you 5.8Ghz system this CP Patch antenna can breath new life into your FPV gear.

I bought this for a friend and he is happy with it. I'll add some updates after he test the range, with the normal immersion mushrooms we got over 1 km clear video on his setup. lets see if these are a better.Great antenna, using with diversity receiver and has a surpringly wide beam width.Works perfect to get the maximum range for my fpv gear.
note that the type of connector fits to your video tx! I had to buy an extra adaptor. And think of the right polarization!happy with this, it improved my range over a clover leaf style sprionet antenna but at close range its very directional and easy to fly too far to one side of the signal.
it would be ideal for a diversity setup but if you only fly close to yourself like in a park or double football pitch size then cloverleaf style spironet type is better IMHO
