A typical LPDA design gain is about 3 dBd down from a typical 3 element
Yagi, and almost 2 dBd down from a typical 2 element Yagi. The tradeoff, as
you have indicated, is a nice flat VSWR over the entire specified bandwidth.

Hmmmm .. just got time to check out the aerial in question .. I THINK
that is the model of the aerial I was involved in installing at Fort
Wainright, in KL7 land -- 1990 --- comm center ..
I assembled and raised that critter, had a complete system, with their
rotator, tower, raising apparatus, etc... whatta brute. Worked swell, but
on 2ØM I flat kicked their butt, from about 3-4 miles away, using a Mosely
monobander @ 72 feet-- 46' boom .. similar power (they, Collins KW.. me,
hotrodded Heath 220 amp) but, that is to be expected . my aerial would not
work too very good on the 15M band .. HIHI ..
Rich . . hope you have found the info you need .. Mark .. AA6DX
