Does the length of a LORAN metal whip matter much?

Yes, it matters a lot. Loran operates at 100 Khz, Very Low
Frequency. The antennas are heavily coil loaded to tune them at this
low a frequency and very narrow banded. The whip length is part of
this tuning and if you change it to a different length the antenna is
way out of tune and not near as sensitive. It may still function out
of tune, but signals will be down.

That's about the same frequency as my sextant works on.
