Any antenna that is less than 1/2 wavelength long and less than 1/2 wavelength high will start to loose efficiency when shortened or lowered. (1/4 wave verticals must also be at least 1/4 wavelength long and have an almost perfect ground plane). So for HF frequencies if you want to go a similar route you should look into magnetic loop antennas.An Introduction to Shortwave Radioby RadiodogTime to get back to basics! What is shortwave radio? Why should you care? In this video, I explore what SW ra...Each time you double the OD of the wire or tubing, you can expect about a 3db increase in efficiency. (1/2 of an S-unit) To make a really appreciable difference, (6db, or 1 S-unit), quadruple the size. For wire, this is pretty easy. For tubing, going from 1/4-inch to 1/2-inch to get a 3db improvement may not be worth it from a weight/cost ... ….
