This is a 10 turn helical antenna for 5.8GHz video receiver. There are plenty of youtube tutorials and websites which outline the build process so I won't document the build process. Here is a list of the other parts you'll need:
1.6mm solid copper wire
Copper coated PC Board I cut it with my mini table saw (https://www.thingiverse.com/thing:1708586).
Coax wire and SMA connector or PCB SMA connector
I printed mine in ABS and used CA glue to hold it all together. I built mine as a RH antenna but I'm pretty sure you could build it as a LH antenna just by flipping one of the frames 180 deg. It's been successfully tested beyond 7km.
Update - Jan 2, 2019
I just realized "Helical 10 Turn - B.stl" was missing a hole, I've updated the STL file. If you printed the previous one, just drill the needed hole.
