Question

For efficient transmission, transmitting antenna has length comparable to
A. `lambda//2 `
B. `lambda // 3 `
C. `lambda // 4 `
D. ` lambda // 5 `

Answer 1

Correct Answer - C
For efficient radiation and reception , the height of transmitting and receiving antennas should be comparable to a quarter of wavelength of the frequency used. So , for efficient transmission of signals of wavelength ` lambda ` , the minimum length of antenna should be ` lambda//4 `
