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.
Please go to our Main Announcement Page for more info:

Thanks for your time & hope to see you soon!
