Free Online Engineering Calculator to find the Dimensions of a yagi Uda Antenna for a given Frequency Range and Length.
30 cze 2022 · The calculator calculates the Yagi-Uda antenna of the DL6WU design with boom-correction (correction for the influence of the load-bearing boom). Calculation is according to the G3SEK-DL6WU method. The antenna is optimized for maximum gain.
8 paź 2023 · For example, for the DAB+ band, the length of a 5/8 λ car antenna can be up to 1.5 meters. How to calculate a five-eighths antenna? The simplest idea is that we just need to calculate the input impedance of a 1.25 λ dipole, and half of that will be the input impedance of a 5/8 λ monopole.
Yagi-Uda antenna calculator. Frequency [MHz]: Director count: Wavelength (λ): 2.08 m = 208.19 cm. Note. The "boom" is the part that holds all the elements, purple on the diagram. The driven element is the part that you connect to your hardware, just like a dipole.
9 paź 2023 · A 5-element Yagi antenna is a directional antenna with a driven element, a reflector, and three directors. Its estimated gain is approximately 8-12 dBi. Element lengths and spacings are calculated based on the desired frequency. Optimal spacing is typically around 0.1-0.2 wavelengths.
4 lip 2022 · The fact is that a Yagi-Uda is not a simple antenna design, but a large class of antennas, which includes an infinite number of practical designs. There are only 3 elements, and by varying the 5 available dimensions (degrees of freedom), we can get an antenna for both 50 and 75 ohms, with different gain, different bandwidth, etc.
