3 paź 2024 · This calculator simplifies the process of designing an EFHW antenna, providing quick results for various amateur radio bands, and helping users build efficient antennas for their specific needs. Recommend
Dowiedz się, jak korzystać z kalkulatora antenowego EFHW, aby określić idealną długość anteny w oparciu o żądaną częstotliwość. W tym artykule przedstawiono przewodnik krok po kroku, odpowiedni wzór (L=468/f) i praktyczne przykłady.
14 sie 2024 · To calculate the length of an EFHW antenna, divide 468 by the frequency in MHz. The result will be the length of the antenna in feet. What is an Efhw Antenna? An EFHW (End-Fed Half-Wave) Antenna is a type of radio antenna commonly used in amateur radio.
15 lip 2024 · The EFHW (End-Fed Half-Wave) Antenna Calculator is a valuable tool for radio enthusiasts and professionals alike, enabling precise calculation of antenna length based on frequency. This calculator simplifies the process of designing and tuning EFHW antennas for optimal performance across various frequency bands.
This calculator can be used to design a Quarter Wave Ground Plane antenna, with radials. The radiating element is a quarter wave (λ/4) and the radials are 12% longer. There are usually four radials, three being a minimum, but you could use up to six.
5 cze 2021 · The Antenna Calculator. for. Half-Wave Dipoles. Enter your desired frequency (MHz) of operation (i.e. 3.55). If you have no particular preference within a given ham radio band, then simply enter its center frequency (i.e. 7.15 for the 40 meter band).
30 lip 2024 · Our dipole calculator is a simple tool that allows you to compute the length of a simple antenna — it'll also provide you with the value of the wavelength and the adjustment factor [k].
