WebSingle-band dipoles are among the easiest antennas to build. All you need is some stranded, noninsulated copper wire and three plastic or ceramic insulators. A 1/2-wavelength dipole is made up of two pieces of wire, each 1/4-wavelength long. Calculating the lengths of the 1/2-wavelength wires is simple. Just grab a calculator and perform the ... 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…

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. WebDipole Antennas - the Effect of Height Above Ground I frequently hear the question: how high should my dipole be? Or alternatively, will my dipole work well at this or that height?

"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. " - How a dipole works
