Oh, thank you! Now if we only had cursers on some popular freqs like 125, 146, 155, 225, 300, 400, 445, 460, 470, 512, 800, 900MHz, etc, it would be even more useful.
Since the actual Discone doesn't work below 100MHz, if your frequency range was 100MHz to 1GHz you would have 200MHz/div and that would be a little easier to estimate SWR at various frequencies. Don't mind me said the guy who used to teach classes on spectrum analyzers and VNAs.
