The Shape of Antennas

Posted on December 31, 2010

I am very curious about the shape of AM antennas and how that shape affects/effects performance.

I am not talking about straight verticals, whether thin wire or thick pipe.

I am talking about towers with either 4-legs or 3-legs which are wide at the bottom, narrow toward the top, and have all the support braces in triangular patterns all the way up each side. What does that wide-bottom narrow top shape do to the signal?
