Chelegance MC-750 Portable HF Vertical Antenna (Image/Thomas Witherspoon, K4SWL) SOTABeams’ Richard, G3CWI, demonstrates how to assemble an 80 through 10 meter doublet antenna. The reason for this has to do mainly with FCC rules, which largely restrict Technician-level licensees to thos This simple multi-band vertical described below will give you very good performance on 40 through 10m and even work relatively well on 80m. HF bands, or high-frequency bands, are radio frequency ranges allocated by regulatory bodies for amateur radio use. but hey, isn't that what antenna building is all about. At about 43 feet in width, the longest element of a 40-meter coil-loaded Yagi is wider than the wingspan of a Piper . I’ve built other split coax loop antenna in the past, but I shared as I was just surprised how well it worked across the whole HF Band, just guessed lengths and very low noise compare to a wire But because it is such a simple and effective antenna for many HF applications, several different methods have been developed to use a single dipole antenna on 2 or more bands.
