1.	Why top loading is used with an antenna?(a) to increase its effective height(b) to increase its beamwidth(c) to increase its bandwidth(d) to increase its impedanceThis question was addressed to me in quiz.This intriguing question comes from Practical Aspects of Sampling in division Multiplexing & Sampling of Bandpass Signal of Analog Communications
Answer» The correct choice is (a) to increase its effective HEIGHT To ELABORATE: Length of an and it’s height are significant parameters for the functioning of the ANTENNA. When length of the antenna is SHORTER than a quarter wavelength (^ʎ⁄4), top loading is used to increase its effective height.
