Yes. We found many years ago that ferrite loops worked fine under bridges
etc with the Loran-C system.  They are also much better  in
high electrostatic fields i.e. thunderstorms.The problem is they are
directional so you have to have two crossed loops with phase
matching.   I have such an antenna on my car now  for
picking up the 300 kHz DGPS transmitters.
