I'm not saying that you
tune an antenna to a particular frequency by changing its length. I'm saying that it
receives signals best at a length that's an even fraction of the frequency it's tuned for.
Sure you can telescope those TV rabbit-ears. But notice that they pick up your selected channel best at a particular length.
