Whip Antenna Calculator

Whip Antenna Calculator

Calculate the quarter-wave whip antenna length using:
\( L = \frac{75}{f} \)
where \(f\) is in MHz.

* Enter the operating frequency (MHz).

Step 1: Enter Frequency

Example: 900 MHz

Derived Formula: \( L = \frac{75}{f} \) with \( f \) in MHz.


Practical Example:
For \( f = 900\,\text{MHz} \), the quarter-wave length is approximately \( \frac{75}{900} \approx 0.0833\,\text{m} \) (about 3.28 inches).
