The HF spectrum (3-30 MHz) is magical. It bounces off the ionosphere, circles the globe, and lets you chat with a retiree in New Zealand while drinking coffee in Ohio. But the antennas required are famously large. A full-wave loop on 40 meters stretches 140 feet. A 3-element Yagi for 20 meters spans over 20 feet on a 40-foot boom.

note that it is not a "cookbook" of measurements but a guide to understanding The HF spectrum (3-30 MHz) is magical
To convince you that the Moxon truly belongs in every HF operator’s arsenal, here is a quick performance matrix (for a 20m antenna at 25 feet height): A full-wave loop on 40 meters stretches 140 feet
