WebA Balun is used to "balance" unbalanced systems - i.e. those where power flows from an unbalanced line to a balanced line (hence, balun derives from balance to unbalanced).As an example, consider a coaxial cable connected to a half-wave dipole antenna shown in Figure 1. Figure 1. An unbalanced transmission line (coaxial cable) connected to a dipole antenna. 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. Current near the ends of the dipole is of necessity small, vanishing at the ends, because electrons, … WebGet a fiberglass push up mast and put the dipole outside. Run the legs at 90 degrees and don't bend them right at the end of the house, they might interact with soffits or fascia, make the 90 degree bend one joist before that. Consider making it a fan dipole. I have a 10/20/40 fan dipole in the attic and it works well.
