WebJul 11, 2024 · To the common-mode, the stub and the parallel section of feedline make a quarter-wave transmission line. Hm, a quarter-wave transmission line at the feedpoint sounds like a sleeve or bazooka balun. These baluns are made from coaxial, not balanced feedlines. And they can be open or short on the feedline end: if they are open, the sleeve … WebMay 8, 2024 · The Velocity Factor (VF) is a property of transmission lines, specifically used with coaxial cables. Since any dielectric permittivity greater than 1 (air/vacuum) will have the effect of slowing the phase velocity of a …

WebFor 2 meters, a chunk of coax of 1 wavelength long = 300/146 which is about 2.05 Meters. To get the optimum performance this value should be multiplied with the coax velocity factor. If your coax has a velocity factor of 0.92, then coax of 1 wavelength = 2.05 x 0.92, which equals 1.886 Meters. ... WebWavelength is calculated by the formula λ=v/f, where “λ” is the wavelength, “v” is the propagation velocity, and “f” is the signal frequency. A rule-of-thumb for transmission line “shortness” is that the line must be at least 1/4 wavelength before it is considered “long.”. In a circuit with a “short” line, the ...
