IMO: The next stage is designing the coil! A long thin coil [like a
Hamstick] requires a longer length of wire than a short 'fat' [note the
quotes] coil [like a bug catcher or a screwdriver].

The hamstick has a higher current taper than the screwdriver or bugcatcher.

The resultant integral of the current and length [in degrees]
[ampere*degrees] of the resulting antenna is higher with the short fat
coil than with a long thin coil. {This assumes the coils are located
approximately at the same location.}

Additional note. 75 inches of wire versus 40 inches of wire at 14 MHz is
only a 1.1 degree difference.
