UHF Antenna Length Calculator

#1

Post by IB4TL »


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).

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
