I think I asked this question before some months ago but can't find it
with google / dejanews and anyway I'm not entirely certain I fully
understood the answer.

I am putting up an inverted vee fed with ladder line and a tuner, that I
want to use from 160 through 10, but mostly on 160 through 40.

The space I have to put it up is large enough for a half wave on 160
and then some.

Since I am feeding with ladder line and a tuner, is there a particular
advantage to cutting the antenna as a half wavelength on 160, or would I
be just as well off to make it as long as I have space for without
considering its actual resonant frequency?
