For a half-wavelength dipole antenna operating at 28.150 MHz, approximately how long would it be?

To determine the length of a half-wavelength dipole antenna at a specific frequency, you can use the formula:

[ \text{Length (meters)} = \frac{150}{\text{Frequency (MHz)}} ]

In this case, the frequency is 28.150 MHz. Plugging the value into the formula gives:

[ \text{Length} = \frac{150}{28.150} \approx 5.32 \text{ meters} ]

Since this is the total length for a half-wavelength dipole, you would actually need to take this total length and divide it by 2 to find the length for each leg of the antenna. This gives:

[ \frac{5.32}{2} \approx 2.66 \text{ meters for each leg} ]

However, it's important to remember that the formula can sometimes give a result in a different form if considering specific adjustments for practical antenna design, which might cause variations in the realized length due to factors like the surrounding environment or the materials used.

In this case, considering standard calculations, the actual total length of a half-wavelength dipole for 28.150 MHz is about 5.32 meters, leading to approximately
