Detailed Solution
Download Solution PDFThe correct option is 4
Concept:
An angle of radiation is the elevation angle of the lowest lobe ‘θ’ for a horizontal antenna is related to the height of the antenna in terms of wavelength ‘h’ by \(\theta = {\sin ^{ - 1}}\left( {\frac{{0.25}}{h}} \right)\)
Hence with an increase in height, the value in the sine inverse function decreases hence the value of θ decreases.
