[Lowfer] Loop antenna question

[Bill de Carle]

What John said makes sense.  With a small square loop at LF the currents in all branches must be pretty much the same.  A few 
years ago I did an experiment with a horizontal loop near or on the ground, using a differential e-field probe to measure 
polarization. The LF signal was horizontally polarized right over the loop but changed to vertical polarization very quickly 
once we moved outside the loop.
