Introduction: Celtic Knot 2 4GHz Antenna

In this video I will show you how to make my new circular

polarised antenna “the Celtic Knot” that I have been working on for some time now. It is an omnidirectional antenna but with all the benefits that come from circular polarization making it perfect for FPV on a fast turning quadcopter.
