Dipole Antenna Length Calculator

This calculator helps you determine the optimal length of a dipole antenna based on the desired frequency of operation. A dipole antenna is one of the simplest and most widely used antenna types, consisting of two conductive elements arranged in a straight line. The length of these elements is critical for efficient signal transmission and reception.

How to Use:

• Enter the frequency (in MHz) for which you want to design the antenna.
• The calculator will compute the total length of the dipole antenna in meters and feet.
• For best results, divide the total length by 2 to get the length of each individual element.

Example Calculation:

Key Notes:

• The calculation assumes a free-space wavelength, so adjustments may be needed for real-world installations.
• Factors like nearby objects, antenna height, and conductor thickness can slightly affect the optimal length.
• For precise tuning, it's recommended to trim the antenna incrementally while testing performance.

Tip: If you're building a half-wave dipole, each element should be approximately 1/4 of the calculated total length.
