Homebrew Ham Radio Antenna Coil Clips

How to use tools you may already have to make low cost, effective antenna coil clips that are easy to adjust.

In Part 2 I have connected 6 radials to the DX Engineering radial plate under the Hustler 4BTV vertical antenna. I show how to make a solid connection, and demonstrate how to pin the ground radial wires in place. If you want the best performance from a ground mounted vertical antenna, installing an effective ground radial system is essential.
