QUESTION 21: The Antenna Reciprocity Theorem states an antennas electromagnetic properties will be the same whether it is transmitting or receiving.

True /False

QUESTION 22: Select the correct statement(s) regarding antenna and RF wave polarization.

		a. a vertically polarized RF wave cannot be collected by a horizontally polarized antenna
		b. right-hand circular polarization is said to be orthogonal to left-hand circular polarization
		c. signals of the same frequency can be transmitted together in an non-interfering manner as long as their polarizations are orthogonal to one another
		d. all statements are correct

QUESTION 23: Depolarization of a transmitted signal reduces the amount of energy transfer between the RF wave and antenna.

True / False

QUESTION 24: Given the following information, determine the SNR in decibels at the receiver: transmitted power [Pt]=100 dBW, free space loss [FSL]=80 dB, noise [N]= -10 dBW, power received [Pr]=[Pt]-[FSL], [SNR]=[Pr]-[N].

		a. [SNR]= 170 dB
		b. [SNR]= 10 dB
		c. [SNR]= 190 dB
		d. [SNR]= 30 dB
