W6IPA 20m Portable Antenna Design using Buddipole Whips

John W6IPA created a 3D project for the 20m portable antenna coil. Its on Thingiverse

I used the Buddipole Featherweight whip that has a 1/4 thread on the base. These antennas are cheap.

Get a couple of BTS IT adapters as it will allow a FW whip to fit onto a 3/8″ stud mount.

You dont need it for the project but its useful to create other antenna designs.

I  use the BST IT adapter at the base of the antenna and a mount in my design

You do need a counterpoise to get best SWR and its possible to lower the whip elements and shorten the counterpoise for use on 17m and 15m
