   one might add that antenna engineering books contain discussions
   of 'continuously loaded antennas', basically elongated
   wire coils.  depending on details, notably 'aspect ratio':
   length vs diameter, measurement tends towards a physical
   half wave of wire, coiled, not end loaded, resonating
   as a _quarter wave_.  toroids, etc and sparks/streamers
   act as end loads.
