DIY Helical FPV Antenna you won't believe how good it is!
For about $4 in parts you can build a helical antenna that provides a huge amount of gain and significantly increases the range of any 5.8GHz FPV system in a drone or RC plane. This DIY video shows you how to do it and I'll be posting more tests of the 5turn and 3turn versions shortly.
If you want to see the realworld tests just jump to 00:26:00 in the video.
