A sloper antenna when resonant produces more gain
than a vertical dipole resonant at the same frequency.
True or false? prove it

Model parameters for sloping dipole: 60 ft at one end
13.3 ft at the other (45 deg slope). *Horizontal dipole
at 60 ft. *Length of both antennas 66 ft. *Sloping dipole
resonant at 7.225 MHz, same length horizontal 7.3 MHz.
Average ground parameters: conductivity 5 mS/m, and
relative permittivity 13. *Horizontal dipole maximum
gain off the sides (As expected). *Sloping antenna
double lobed pattern with maximum gain at 80 degrees
either side of lowest end. *Softwa Nittany's GNEC.

The original question said VERTICAL dipole , but you modeled a
HORIZONTAL dipole? Or was one of these just a typo?

FWIW, I modeled your horizontal dipole in EZNEC and came up with
slightly DIFFERENT results:
Resonant frequency about 7.335 Mhz
Resistance about 81 ohms
Max gain about 6.54 dBi at 30 degrees
I am INexperienced in using EZNEC and wonder if I'm doing something
wrong?
