Hi Paul I have used your Moxon calculator for 2 antennas. One for 24 MHz the other 18 MHz using Ali tubes. The calculator is spot on and no SWR adjustments required. Thank you. I am Amazed. Michael ZS1RJQ. G8RJQ. Just a little feedback regarding your online Moxon calculator. I used another calculator online, built and tested an antenna, seemed ok until I bought a NanoVNA and found that the antenna was actually resonant a whole 1 MHz below the intended frequency! Re-built the antenna using your calculator, it’s now within 50Hz of my design frequency, way better. I’ll put it to the test in the next few days, see how it performs, many thanks.
