Dipole Antenna Length Calculator

Calculate the total length of a half-wave dipole antenna using the rule-of-thumb:
\[ L_{\text{ft}} = \frac{468}{f \,(\text{MHz})} \]
and convert to meters.

* Enter the operating frequency in MHz.

Step 1: Enter Frequency

Example: 14.0 MHz

Derived Formula: \( L_{\text{ft}} = \frac{468}{f \,(\text{MHz})} \) and \( L_{\text{m}} = L_{\text{ft}} \times 0.3048 \)


Practical Example:
For a frequency of 14.0 MHz:
\( L_{\text{ft}} \approx \frac{468}{14.0} \approx 33.43\,\text{ft} \), which is about \( 10.20\,\text{m} \).
