WebThe basic formula for determining the wire length of a center fed, 1/2 wave wire dipole or inverted Vee antenna (30 mhz or less) is 468/freq-in-Mhz for feet and inches or 143/freq-in-Mhz for meters . The inverted Vee antenna legs will be longer by 2 - 6% from those of the horizontal antenna depending on the angle. WebTuning a Dipole Antenna for Resonance! Find a Ham Radio Dipole Resonant Length. Most dipoles will require a little "trimming or adding" to resonate at the desired frequency. Here is a good recommendation in 7 steps. 1. Cut your dipole wire some 2-3 % longer than the length given by the standard formula. 2. WebThe dipole antenna is cut and bent for effective radiation. The length of the total wire, which is being used as a dipole, equals half of the wavelength (i.e., l = λ/2). Such an antenna is called as half-wave dipole antenna. This is the most widely used antenna because of its advantages. It is also known as Hertz antenna. compass tiffany
