One more thing is not clear to me:
If I use a 1/4 wave wire, where are the 6000 ohms?
Near the feed point or on the far end?

Hi Andrea,

At the far end. Think of the antenna as a resonant transmission line
(meaning it is not terminated in its characteristic Z) and that hi
impedance at the end is transformed through the length to the lower 30
- 50 Ohms typically encountered (accumulating real resistances of the
wire and radiation resistance along the way).
