Lou,
That tilt-over base seems like a neat idea. How tall is it?
Would I have to worry about that capacitor if I don't get the add-on 80
meter kit? I'm primarily interested in a vertical for bands above 40
meters. I might even like a vertical on 40, but not having one wouldn't
disappoint me all that much.
Steve
