Topband: Monopole Radiation Patterns, takeoff angles etc

[Mike Waters]

I've never operated mobile, but it sounds like you're saying the daytime
local range on 160 and 10 is comparable.

But Rich is also talking about the radiation at zero degrees bouncing off
the ionosphere and returning to the earth at some distant point. That's
what I'm wondering about. Local is one thing, but DX is another.
