I have just finished the installation of a Butternut HF6V vertical antenna.
The link below contains several close-up pictures of the ground radial plate
and the coil/capacitor assemblies, which are part of the HF6V. I use the
antenna mainly on 40 meters, but it does work on 80-10 meters and 30 meters.
