Folded dipole antenna (parametric)

Parametric folded dipole antenna (support).

Disclaimer: This antenna is hard to build and hard to fine tune. For 2.4GHz, the segments are small and each solder can impact the performance. If you don't have a antenna analyzer like the N1201SA, you will probably waste time and money trying to build it.

Once printed, you just have to bend the wire around. You can keep the support for your final antenna to make it deformation proof.

Edit in the .scad:
* the frequency (in MHz)
* cable velocity
* the wanted height
* and other things if needed

Or open the thingiverse Customizer.

It is computing all you need to make the antenna, also the shielded wire length (informations are printed in openscad console). In millimeters.
