Wow! I'm really glad I asked the "dumb question"... Thanks for all
the illuminating answers.

A 43 foot vertical or end-fed or a 86' dipole.
I created a spreadsheet several years back that found all of the
non-even harmonic radiator lengths from 160-6m and then graphed the
points so you could visually "find" gaps in the graph to pick your
antenna length. It even had an option for dipoles and loops.

Subject: [Flexradio] Questions about antennas and spectral displays...
I think I know the answer, but I want to double check... That 43
foot antenna... is it an end-fed random wire off the back of the
tuner? or a center-fed dipole, with total span 43 feet?
Also, as a side question... Anyone happen to know why all the other
higher-end modern rigs (Icom, Kenwood, Yaesu, Ten-Tec), use swept
spectrum analyzers instead of using an FFT like Flex Radio uses?
