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**
