T he vertical is a popular antenna among hams who lack the space for a beam or long wire antennas. In an electrical sense, a vertical is a dipole with half of its length buried in the ground or “mirrored” in its …
WebIt will also be tricky to match the antenna on other bands, particularly where the antenna is a half-wave long at your operating frequency and presents a high impedance at the feed point. One solution is to choose a length of wire that offers neither a particularly high or low impedance on any of the bands you wish to operate on. Webmost backyard antennas, the average ham is lucky to achieve an antenna height of 1 wavelength on 10 meters, while the truly fortunate operator may get his wire to 1 wavelength on 17 or 20 meters. Every horizontal antenna is subject to essentially the same general phenomena that affect horizontal dipoles in terms of their height above ground.
WebActual long-wire antennas require a length greater than a quarter-wavelength (λ/4) or half (λ/2) of the radio waves (most consider a true long wire to be least one wavelength), whereas random wire antennas have no such constraint.
