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
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 · Using the EFHW Antenna Calculator is straightforward: Input Frequency (MHz): Enter the operating frequency of your radio equipment in megahertz (MHz). Calculate Length: Click the “Calculate Length” button to determine the recommended length of the EFHW antenna.
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.
23 lut 2023 · I explain the basics of the End Fed Half Wave (EFHW) Antenna, and how i calculate the lengths of my antenna for my targeted bands. I also go over some harmonics and how this can be used to combine a couple of bands on a single antenna.
19 sty 2017 · Some wire antennas with a vertical polarisation like a quarter wave vertical have to have lower take-off angles than a horizontally polarized like a dipole made from wire strung up between the trees in a back yard. To calculate the lenghts: a rule of thumb for a dipole wire antenna length is: dipole length (in feet) = 468 / f (MHz)
