Default 75 meter hamstick vs low dipole

Frank's wrote:
Assuming a 7 ft monopole, with a lumped element inductor
(located in the middle of the vertical) of Q = 500,
and 100 W input. The total radiated (sky wave) power is 1.4 W.
The gain is -12.7 dbi with a take-off angle of 23 degrees.
At resonance the input impedance is 14 ohms.


And the Q of a hamstick is probably a lot closer to 50
than to 500. Someone else reported the hamstick as -20 dBd.
