This tool calculates the length of a Full Wave Dipole Antenna
Calculator
- Enter the Operating Frequency
- The tool will compute the antenna length (L).
- Use the drop down menu to select the units for both input and output
Example Calculation
For a frequency of 100 MHz, a full wave dipole has a length of 2.85 meters or 9.36 feet.
Formula
The total length (L) of the dipole antenna is calculated as:
In Feet
L = 936 / f
In Meters
L = 285 / f
where f is the frequency in MHz
What Is a Full-Wave Dipole Antenna?
A dipole antenna is one of the simplest and most commonly used types of antennas. It consists of two conductive elements (usually wires or metal rods) that are equal in length and positioned in a straight line. In a full-wave dipole, the total length of the antenna is equal to one full wavelength of the frequency it is designed to transmit or receive.
This is in contrast to the more common half-wave dipole, where the total length of the antenna is half the wavelength of the operating frequency.
A full-wave dipole can provide more gain and directivity, making it more efficient in certain applications, particularly in high-frequency (HF) and very high-frequency (VHF) communications.
Key Characteristics of a Full-Wave Dipole:
- Total length: Equal to the wavelength of the operating frequency.
- Directional gain: A full-wave dipole provides better gain and more focused radiation patterns than a half-wave dipole.
- Common uses: Used for high-frequency applications, long-distance communication, and certain broadcasting purposes.
Why Use a Full-Wave Dipole Antenna Calculator?
To ensure optimal performance, the length of the full-wave dipole antenna must be precisely tuned to the frequency you intend to use. If the antenna is too short or too long, it will not resonate correctly with the frequency, leading to poor signal transmission and reception.
A full-wave dipole calculator helps you quickly determine the correct length for your antenna based on your desired frequency. This allows for accurate and efficient antenna design without the need for complex manual calculations.
