Hello,

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

My poor knowledge of antenna systems think that the ATU, choosing the
appropriate LC value, bring the entire system in a resonant condition:
true or false ?

And , second question, because a friend of mine own a MFJ 269 analyzer,
how i can *approximately* have an idea of the efficiency on a frequency
F for my whip ?

Thanks in advance,

The tuner will provide an impedance match to your transceiver (50 ohms). *
It won't make your antenna resonant on 20m (or any other band, other than
2m).- Hide quoted text -

I think "CQ" meant the whip was 2 meters long. That would be 1/4 wave
on 38 MHZ if I did the math right. This is the 8 M band? The tuner
might get it on 20 M, but 40 M will be a stretch.
