9. Why would one need to know the feed point impedance of an antenna?
a. To match impedances in order to minimize standing wave ratio on the transmission line
b. To measure the near-field radiation density from a transmitting antenna
c. To calculate the front-to-side ratio of the antenna
d. To calculate the front-to-back ratio of the antenna
10. What is meant by antenna gain?
a. The ratio relating the radiated signal strength of an antenna in the direction of maximum radiation to that of a reference antenna
b. The ratio of the signal in the forward direction to that in the opposite direction
c. The ratio of the amount of power radiated by an antenna compared to the transmitter output power
d. The final amplifier gain minus the transmission-line losses, including any phasing lines present
