3D model description

5GHz helix antenna.

Can be printed using "Vase mode" 0.28 mm layer, 0.8 mm line.

Use included .scad file to switch polarity, adjust length - or diameter, if you'd like to print a helix for a different frequency. Fully customizable!

Drill a small hole at the top and stick the wire inside to finish and prevent from unwinding.

Glue the base to a piece of copper laminate, run a quarterwave segment of wire parallel to the ground to provide matching to 50 Ohm.

Use antenna analyzer to check for impedance and reflected wave before transmitting.
