This tool calculates the physical dimensions of a 80 meter dipole antenna.
80 m refers to the wavelength of the transmitted and/or received signal.
Using the calculator below at 80 meters,
- The dipole length (L) is 124.9 feet
- The length of each element of the dipole (l) is half of that at 62.45 feet.
Formula
The total length (L) of the dipole antenna is calculated as:
L = 468 / f
where f is the frequency in MHz.
f is calculated from the wavelength. For 80 m the frequency is 3.75 MHz.
The length of each arm of the dipole
l = L/2
