[Lowfer] WM Lowfer - relocated antenna

Thu Jul 7 17:18:17 EDT 2016

Mike,
      For a full wave loop (like a cubical quad for example), you would be 
correct, maximum radiation off the 'faces' of the antenna i.e. at 90 degrees 
to the plane of the loop. For an electrically small loop, maximum radiation 
is off the ends, if your loop wire is oriented N-S, then maximum radiation 
will also be N-S.
    When I started out, I was under the same impression that you have, but 
Bill Ashlock corrected me.
