[Elecraft] 80 Meter Verticals

[Ron D'Eau Claire]

I know them as fan antennas. The old UHF "bow tie" TV antennas are a good
example. 

The discussion about radiation resistance vs. feed-point resistance is
specious. When feeding more than one resistance in series, such as a
monopole impedance and a ground impedance, Ohm's law prevails. The higher
resistance consumes the most power. So techniques to reduce the ground R or
increase the antenna feed point R all contribute to more radiated power.

way to make a broadband antenna. This design has a name, but it escapes me
right now.
