Chapter 26.2, Problem 27SSC

To determine

To Explain: The importance for a parabolic dish receiving antenna to be aimed directly towards the transmitter.

Explanation of Solution

Introduction:

An antenna is a sequence of conductors which are attached by electric means to the receiver or transmitter. Antennas are designed in such a way that these can transmit and receive radio waves in all horizontal directions.

Depending on the geometry of the shape, the parabolic dish receivers are more able to receive the signals among all the different shaped receivers within a very narrow range of angles. Caution must be taken while aligning the receiver with the antenna in order to optimize the intensity of a receiver signal, because of the very small angle range.

Conclusion:

Hence, depending on the geometry of the shape, the parabolic dish receivers are more capable of receiving the signals within a very narrow range of angles.
