I've been curious about log periodics myself.

The ARRL Antenna Handbook 17th Ed. has a 5 band (13-30mhz) design on a
26 ft boom with 12 elements.

The article text on pg 10-10 states in part:  "...this is a large array.... 
with the same gain
one would expect with a full size two-element Yagi array:"

I acknowledge the benefits of the LP including bandwidth, feed impedance, etc.
but for a 26 ft boom and 12 elements I'd hoped for more than 2-element
Yagi performance.
