Little Wil Ground Plane Adapter

thingiverse

This adapter allows you to add ground plane radials underneath a Little Wil antenna instead of using the magnetic mount and a flat ground plane. You can modify the angle of the radials, the number of rods and their diameters. To mod the antenna, you have to first remove the bottom paper-like cover sheet, unscrew the nut and then remove the magnet. Once that's done, you can place this adapter where the magnetic component was, screw the nut and attach your radials. You have to make sure that all radials are electrically connected to the center screw, which is connected to the ground of the coax. How you do that is up to you and the material you choose for the radials.
