Use our **Dipole Antenna Length Calculator** to quickly determine the ideal length for your half-wave dipole antenna based on frequency. Essential for ham radio, shortwave, and general RF communication, ensuring optimal performance and SWR. Calculate wavelength and antenna length effortlessly for precise tuning.
Formula:
For a half-wave dipole antenna, the approximate total length is calculated using the following formulas:
Total Length (feet) = 468 / Frequency (MHz)
Total Length (meters) = 142.6 / Frequency (MHz)
Where:
- Total Length = The approximate physical length of the dipole antenna for resonance.
- Frequency (MHz) = The desired operating frequency in Megahertz.
Wavelength is calculated as:
- Wavelength (meters) = 300 / Frequency (MHz)
- Wavelength (feet) = 984 / Frequency (MHz)
