For efficient transmission of signal , the height of antenna should be at least equal to (1/4) th of signals wavelength . In case an EM wave of frequency 1 M Hz is to be transmitted, What shall be the minimum height (in meters) of the antenna
75
150
300
600
For efficient transmission, the height of antenna should be comparable to quarter of wavelength.
Given the frequency =
Wavelength of an electromagnetic wave = c/f
Minimum length of antenna = d/4
= 75 m
