I didn't fail to explain them, Roy, you just failed to listen
to reason, ploinked me, and started uttering Big Lies about
me.
In my 75m mobile base-loaded bugcatcher antenna:
1. The coil occupies ~25 degrees of antenna.
2. The impedance discontinuity at the coil to stinger
junction provides a ~44 degree phase shift.
3. The stinger occupies ~11 degrees of antenna.
At resonance the antenna is electrically
25+54+11 = 90 deg long even though it is physically
only ~12 degrees long.
All of the "missing degrees" appear at the impedance
discontinuities but you already know that since I
explained this to you two years ago.
