About This Calculator
This calculator uses the formula L = 468/f where:
- L is the total length of the dipole antenna
- f is the desired frequency in MHz
- Each leg of the dipole is L/2 long
Note: This calculation provides a starting point. Fine-tuning may be needed for optimal SWR based on installation height, surrounding objects, and wire diameter.
