Because I was asked - Best Vertical

Because I was asked, the best vertical of those I've made: 1. 1/4 wave Ground Plane : Smaller than many others, light weight, easy to mount, simple to build. Wide-banded, easy match. No matching network required which translates to diminished losses. Potential to handle lots of power because there i...
