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).
Antenna Length Calculator. 1. What type of antenna do you want to build? Dipole. Fan Dipole. Inverted Vee. Off Center Fed Dipole. Vertical. 2. What frequency will you be operating on? Frequency: MHz. Meters Feet. 3. Here's your antenna...
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].
Dipole Antenna Calculator. The measurements below are for building a simple Dipole Antenna. The Wire Size can range from 16 AWG to 12 AWG. The larger the wire, the wider the bandwidth. The antenna is designed to be fed with 50 or 75 Ohm Coax Cable of most any length with a Balun.
Actual resonant antenna lengths can vary with antenna height, ground conductivity, and proximity of surrounding objects. Start with a longer antenna length and adjust the legs in equal increments for minimum VSWR.
14 sie 2024 · The following steps outline how to calculate the length of an Efhw Antenna using the formula: L = 468 / f. First, determine the frequency (f) in MHz. Next, use the formula L = 468 / f to calculate the length of the antenna (L) in feet.
This calculator is designed to give the vertical length (height) of a particular antenna, for the frequency and wavelength chosen. This does NOT take into consideration the type or size of horizontal reflectors, of even if there is a need for them.
