The only reliability problem I've read of was salt-encrusted antenna
insulators intermittently breaking down late in a voyage.  One could
estimate time at sea by the quality of the note.

Yes indeed communication was almost exclusively HF, but note that
everyone had MF capability.  Antennas were typically three wires fore
and aft from the conning tower, and presumably tied together and worked
against sea water ground for MF.  This is not really efficient at MF,
but will work well enough for communication.
