Question 1 of 27070

What point on a shipboard antenna system displays the maximum potential?

🔍 Key Concepts

• Voltage distribution along a resonant antenna (like a half-wave radiator) • Relationship between current nodes and voltage antinodes on an antenna • How the feed point (transmission line connection) usually differs electrically from the free end(s) of the antenna

💭 Think About

• On a simple shipboard whip or Marconi antenna, where is the current usually highest: at the feed point or at the free end? How does that relate to voltage? • Think about a vibrating string fixed at one end: where are the displacement peaks? How is that similar to standing waves of voltage and current on an antenna? • Which part of the antenna is most "insulated" or farthest from any low-impedance connection to the transmitter/ground system, and what does that imply about potential there?

✅ Before You Answer

• Make sure you distinguish between maximum current and maximum potential (voltage) — they occur at different physical points on a resonant antenna. • Confirm in your mind where the feed point is located and what kind of impedance (high or low) it normally represents. • Visualize or sketch a standing-wave pattern of current and voltage along a half-wave or quarter-wave antenna before choosing an answer.
