============================================================
LPDA Notes - Volume 3: A Potpourri of LPAs
L.B. Cebik,  W4RNL

Volume 3 of this series takes a broader view of
log periodic  arrays (LPAs).

Includes 95 Modeling Files

Beginning with two  further studies into LPDA design factors, 
the first chapter addresses the  role of shorted stubs attached 
to the center of the longest element, as they  function to move 
the frequency of anomalous frequencies, but fail to remove  the 
anomalous behavior.

A companion study looks into the periodic  nature of current 
maximums and minimums along a set of LPDA elements under  varying 
conditions of phase-line characteristic impedance, element  
diameter-to-length ratios, and other design factors.

Thanks for your time  & hope to see you  soon!
