Which two measurements are mentioned together with antenna height?

• A. Antenna height from the waterline and approximate battery strength
• B. Antenna length and cable type
• C. Battery temperature and solar panel efficiency
• D. Water depth and sea state

Answer: (A)

When evaluating how well a maritime communication or sensing setup will perform, you often see antenna height paired with energy status. The height above the waterline establishes the line-of-sight range and radio horizon, which determines how far the signal can reach over the curved surface of the Earth at sea. Pairing that with the approximate battery strength provides a quick snapshot of whether there is enough power to transmit with sufficient intensity to achieve that range, and for how long the system can operate. The other options describe hardware dimensions or unrelated environmental factors, which don’t form the typical measurement pair alongside antenna height. Antenna length and cable type are physical specifications, battery temperature and solar panel efficiency concern energy conditions, and water depth with sea state are environmental factors, not measurements that are commonly cited together with antenna height.
