According to 75m mobile shootout results, an ATU driven whip is ~8 dB
down from a base-loaded bugcatcher because the bugcatcher coil
radiates and an ATU is usually shielded and often uses powdered iron
toroids for the coils.

Yes, understand *perfectly*. My energy go somewhere, and this "somewhere" is
heating some toroid into a shield case or radiate on the air. Conservation
law.

Center load i think mean also lower ground loss, IIRC.

And as i understand, a RX shootout of the mobile whip compared with my full
size 1/4 wl vertical antenna with the same transceiver, to have a suitable
relative dB comparison, can give the best test measure i can do with my
actual equipement.

Thanks Cecil an other posters, other suggestions or links to learn more are
very appreciated.

While that is true your exiting installation may be better than you
think. Best Antenna can be subject to to any number of parameters
from greatest gain to practical operations and installation to
significant others opinion of aesthetic appeal.
