Enter the frequency into the calculator to determine the length of a 5/8 wave antenna. This calculator can also evaluate the frequency, given the length of the antenna is known.

## 5/8 Wave Antenna Length Formula

Y = (2 * (L + W) + E) / 36

The following formula is used to calculate the length of a 5/8 wave antenna.

L = 585 / f

Variables:

• L is the length of the antenna in meters
• f is the frequency in MHz

To calculate the length of a 5/8 wave antenna, divide 585 by the frequency in MHz. The result will be the length of the antenna in meters.

## What is a 5/8 Wave Antenna Length?

A 5/8 wave antenna length refers to a type of antenna design where the physical length of the antenna is 5/8 of the wavelength of the frequency it is designed to receive or transmit. This design is often used in vertical antennas for radio communication systems, as it offers a lower angle of radiation and greater range of signal compared to other designs. The 5/8 wave antenna is particularly popular in mobile communications, such as for car radios, because of its superior performance in transmitting signals over a horizontal plane.

## How to Calculate 5/8 Wave Antenna Length?

The following steps outline how to calculate the length of a 5/8 Wave Antenna using the formula: L = 585 / f
