Chapter 26, Problem 62A

To determine

To Find: Length of an antenna having frequency band $\text{94}\text{.5 MHz}$ .

Answer to Problem 62A

The length of the antenna is $3.17\text{m}$ .

Explanation of Solution

Given:

The receiving frequency is $94.5\text{MHz}$ .

Formula:

The length of an antenna in meter is given by

Length in meter = $\frac{\text{300}}{\text{Frequency }\left(\upsilon \right)\text{in}\text{MHz}}$   ...... (1)

Calculation:

Substitute $94.5\text{MHz}$ for frequency in equation (1)

  $\begin{array}{c}\text{Length in meter} =\frac{300}{94.5}\\ =3.17\text{m}\end{array}$

Conclusion:

Hence, the required length of the antenna is $3.17\text{m}$ .
