Doesn't matter if the radiation pattern changes, if you can still receive
the signal you still know the direction.

LORAN is ultra low frequency,,, isn't it?

LORAN-A operated in the 1,750-1,950 KHz frequency band prior to deployment
of the more accurate LORAN-C system.
LORAN C is 90 to 110 kHz band.

I don't know if it's still in use nowdays,but there is/was a very low
frequency antenna buried in the ground from coast to coast along the
U.S.A./Canadian Border.I read about it in either one of my Popular
Science or Popular Mechanics magazines which dates back to the 1950's or
1960's.If I sort of remember,that antenna is intended for U.S.Navy to
use.Maybe it is an ULF antenna,I still have that magazine floatin around
here somewhere.

Might have been Project ELF
