Half wave dipole calculator
WebThe directive gain of a half-wave dipole is known to be 1.64 and it can be made nearly 100% efficient. Since the gain has been measured with respect to this reference antenna, the difference in the gain of the test antenna is often compared to that of the dipole. The “gain relative to a dipole” is thus often quoted and is denoted using ... In order to use our antenna calculator, you'll need to know the frequency on which you want your antenna to operate.. Your result will consist of: Your total antenna length (L);; Length of one arm of the antenna (l); and; Wavelength, as well as its portions: 1/2, 1/4 (it'll also allow you to use it as a 1/2 wave dipole calculator).; In the advanced mode:. You may enter the diameter of your ...

WebTaking the common half wave dipole which has a gain of 1.64 (2.15dB), A e =1.64λ 2 /(4π)=0.13λ 2. For example, A e for a lossless 7MHz half wave dipole is about 240m 2, whereas the projected area of the dipole conductors is more like 0.04m 2. Clearly you cannot run a tape measure over the dipole to obtain its effective aperture.
WebA half-wave antenna has a radiation resistance of: much larger than for a Hertzian dipole antenna! It is therefore a much more efficient radiator.
