Guess again.  Perhaps your next guess could account for why a 3/2
wavelength antenna is (462*2.95)/freq.

The .95 factor is for what is sometimes called 'end effect'.  There
are capacitive effects seen at the ends of the dipole that make it
seem electrically longer than it is.  The .95 is a correction for
that, so that it will come out to the right frequency.
