Default Resonant condition

Hello,

my mobile setup is composed by a 2 meter vertical whip feeded immediately
close to it by an automatic antenna tuner.


Thanks to all. Now is a clear statement that my problem is measuring the
"inefficiency" of the entire system

Only to mention that due to a sort of "quiet life way" with the neighbors,
my home setup is a ATU CG-3000 feeding 9,5 meters height monopole with about
40 random lenght radials (from 5 to 20 meters of lenght) and electrically
connectet to 200 square meters of chicken fence, with real chickens inside
perform quite well on 80, from 40 to 12 meters is probably the best
antenna i ever had compared to old dipoles, in 10 maybe it is too close to 1
WL... but work almost all , even in furiouses pile ups.

Now that I annoyed with this info, the conclusion of the OP or the third
question if you want: how it is possible that mobile setups with the
"motorized" antennas can have a minimum of efficiency in 40 meters ?? What
the difference from a variabile motoryzed L and an ATU at the feed point ??
Or i miss something important about the 2 feeding methods ??

TIA,
-.-. --.-
