D
Answer
Basic radio theory
Type
A
Pointed down to bounce the signal off the ground
B
Pointed towards the station you are contacting
C
Pointed at the horizon
D
Away from your head and away from others
Answer Notes
When transmitting with a hand-held transceiver (HT), the antenna radiates radio frequency (RF) energy close to your body. To minimize RF exposure, you should hold the radio so the antenna is positioned away from your head and away from others.
Distractors like 'pointed towards the station' are incorrect for two reasons. First, safety is the primary concern of this regulation. Second, most HT antennas are omnidirectional whips, meaning they radiate strongest from their sides; pointing the tip directly at the target actually results in the weakest signal.
