Shown coiled-up for shipping. In use those four loops are uncoiled and straightened out.
But I occasionally want to use PSK31 on 80m too, and that's centered down on 3.580 MHz. I could go through an hours' exercise in adjusting the outer ends each time I want to change sub-bands, or just:
clip on an extra length of wire to each end of the dipole to lower the resonant frequency. In practice, it came out to about 12" for these tip wires, but if you're tuning from scratch start with about 20" and trim it down a couple of inches at a time. The black clip on the left attaches to the end of the antenna; the red clip on the right holds things stretched out with paracord and a little ceramic insulator. Once everything's tuned up, it takes about 2 minutes to step into the back yard and attach/detach the tips to switch sub-bands. It even pulls in the bottom-end of the Extra-class phone band, a nice bonus.
It took an hour or so to trim everything just right, but it's worth it to get PSK31 coverage on 80m. Because PSK31:
It's kind of like The Matrix, only much, much nerdier.
