This is post 2529 in a continuing series of simple ham radio antennas.

Thanks to "SA2CLC" for this fascinating and oftentimes inspiring tutorial on how to make an antenna loading coil.

The key to this project is some plastic and a 3D printer, which makes the coil easy to build.

Here are some comments from "SQ2CLC":

Here is montage of me making a loading coil for vertical antennas from scratch using the Ender 3 3d printer. The coil form is printed in PETG at high resultion. I have desgned the coil using fusion 360, with inspiration from an OK1CDJ design if I remember correctly. I set up the antenna using a 6m fishing rod, 2 radials, each 5m long. The radiator was cut to give good SWR at 20m with shorted coil, and then 30, 40 and also 60m could be matched using the coil. Thanks for watching. .stl at thingiverse: https://www.thingiverse.com/thing:452... Music: Jahzzar, Take Me Higher https://freemusicarchive.org/music/Ja...
