The UHF (Very High Frequency) range is 300 MHz to 3000 MHz (3 GHz). Use this calculator to find the dimensions of a Dipole antenna designed to operate at this frequency range.

A half-wave dipole antenna is comprised of two quarter-wavelength conductors placed end to end [1].

This calculator gives the **length of a half wave dipole antenna**. Enter the Frequency and the tool will compute the antenna length (**L**).

## Example Calculation

At a frequency of operation 1000 MHz. The dipole length (**L**) is **5.62 inches** or **0.14 meters**.

The dimensions are smaller than that of a VHF antenna that operates at a lower frequency.

**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.

The length of each arm of the dipole

**l = L/2**
