David,

Good topic with longevity too #!:?} Some random
comments.

1.  Construction quality and rough weather
survivability.

*(Always a factor).

2.  SWR within the desired bands.

* (10 through 30 Log Periodics operate on all
frequencies from 10 through 30 meters), not like
monobanders, Tribanders.   LP's have a typical
highest VSWR about 2:1 across the entire band!).

4.  F/B, F/S ratios ... can make all the
difference when QRM threatens
     a QSO.

* (Any is better than none, but the yagi
displays the best F to B and F to S signal to
noise ratio).

5.  Gain -- using essentially identical criteria
(looking for differences
over 2dB as significant).

*(The gain of 3 dB will double your power out &
make a discernible increase in hearing, that is
defined as a noticeable change in audio).

Ah, the bigger the better.  Axiom her in
Michigan:  If your wire antenna's didn't come
down last winter, they weren't big enough hi hi.
