Verticals … radials … what’s the right thing to do?
Even though I have a Butternut vertical in the antenna arsenal, this .pdf file from SteppIR, is one of THE best articles about radials that I have ever read. It’s in “plain ol’ English” and doesn’t require you to have a Doctorate in RF Theory to understand it. Just thought I would share!

I currently have about 50 radials under my Butternut. Looks like I could stand to add some more next Summer – although I’m currently close to the point of “no extra benefit”. Looks like with about 25 more, I can get a bit closer to that 90% efficient point. And “next time” (if there ever is one), I will seriously consider NOT ground mounting my next vertical.

Thanks for sharing this Larry. It is well written and informative. I can use to “tune up” my vertical.
Thank you for the article. I have a GAP Challenger, my third GAP antenna, had a Challenger about ten years ago, sold it to try a Titan, which I sold when my tower went up..no room for both. Now back to the Challenger, great antenna, have heard a lot of good things about the Butternut as well. When I had my first GAP antenna, tried the more radial the better route, had 32 I think it was when all was said and done. Only run three as is recommended never had any better or worse function either way. For some verticlals, radials are a must, others not so much. To each his own, but I will read this article, maybe get a few pointers in the process, anything to make an antenna function to its optimum.
