Question:

If \(\lambda\) is the wavelength of radio signals to be transmitted, then what is the length of Hertz antenna ?

Options:

\(\lambda\)

\(\frac{\lambda}{4}\)

\(\frac{\lambda}{2}\)

2\(\lambda\)

Correct Answer:

\(\frac{\lambda}{2}\)

Explanation:

A hertz antenna is a straight conductor of length equal to half the length of radio signals to be transmitted or received i.e. l = \(\frac{\lambda}{2}\). This antenna is not grounded.
