Calculate half-wave dipole antenna length for ham radio frequencies
Each leg: 1.63 feet
A dipole antenna is one of the most common and fundamental antenna types. The formula Length = 468 ÷ Frequency calculates the total length for a half-wave dipole in free space, accounting for the velocity factor of wire.
Note: This calculation provides the theoretical length. Practical antennas may need slight adjustments based on wire thickness, height above ground, and surrounding objects.
