The VHF (Very High Frequency) range is 30 MHz to 300 MHz. Use this calculator to find the dimensions of a Dipole antenna designed to operate at this frequency range.
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 · To calculate the length of an antenna, you may use the formula: L = 468 / f. l = L /2. where: L — Length of the dipole antenna; l — Length of each arm of the dipole; and; f — Frequency. Dividing 468 by the antenna frequency will give you the length of the antenna in feet.
7 paź 2024 · Formula. The total length (L) of the dipole antenna in feet is calculated as: L = 468 / f . where f is the frequency in MHz. A dipole antenna is comprised of two arms of equal length . l = L/2. How to Calculate the Dipole Length. Enter the antenna’s frequency of operation with the appropriate units Hz/kHz/MHz/GHz.
The 5/8 wave antenna consists of a vertical radiator fed at the bottom of the antenna. A matching device should be used if you feed it with coax. Enter the formula for the antenna (normally 585/f or 178.308/f for metric):
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.
30 lip 2022 · The formula for the length of a dipole antenna (calculate the length from frequency and wavelength); The dependency of the antenna length on the diameter of the conductor; and How to use our dipole calculator.
