This is indeed an interesting result, even though it's small. As a
dipole or monopole gets shorter than a resonant length, the current
distribution changes from sinusoidal to triangular.


Actually, it just moves to a straighter portion of the sinusoidal
curve. The cosine curve from 75 degrees to 90 degrees does resemble
a triangle but it is not a straight line. Assuming a triangle from
75 deg to 90 deg is a simplified shortcut that introduces almost a
1% error at 82.5 deg.
