WebA resonant coax-fed dipole antenna will have a low SWR and will radiate efficiently on the band for which it is resonant, but it will not work well on all bands. For example, if the tuning range of your tuner has a sufficient range, you will be able to load up any antenna with it, but it will not necessarily radiate a signal efficiently. bircham tofts

Webdipole: [noun] a pair of equal and opposite electric charges or magnetic poles of opposite sign separated especially by a small distance. a body or system (such as a molecule) … A short dipole is a dipole formed by two conductors with a total length ℓ substantially less than a half wavelength (1/ 2 λ). Short dipoles are sometimes used in applications where a full half-wave dipole would be too large. They can be analyzed easily using the results obtained below for the Hertzian dipole, a fictitious entity. Being shorter than a resonant antenna (half wavelength long) i…

WebFigure 7.1 illustrates operation of a basic half-wave resonant dipole antenna. Shown in Figure 7.1(a) is a dipole antenna excited from an RF source. The balanced nature of the ideal circuit ensures that identical current will exist on each side of the dipole.
