I just finalised a Helix antenna I printed over the night.
Pictures are showing the concept, and assembly.
Everything was almost first time right.
I could adjust the impedance, but I am not 100% happy about the results.
I wonder how I can move the 2nd deep to approximately match with 2.4 GHz (now at approx. 2.2).
Could not attached 3D files as too big, but will share on request.
Any suggestions would be very much welcome.
