What is the transmitting range of most NAVTEX stations?

The transmitting range of most NAVTEX stations is typically 200-400 nautical miles (360-720 km). NAVTEX is a coastal warning system that broadcasts maritime safety information, such as navigational warnings and meteorological forecasts, primarily to vessels at sea. The design and operation of NAVTEX stations allow them to effectively provide coverage within this range, catering to the needs of shipping and maritime operations by ensuring that vital information reaches vessels operating in coastal waters and beyond.

This range is determined by several factors, including the power of the transmitter, the frequency used (518 kHz is the standard for NAVTEX), and the characteristics of the receiving equipment on vessels. The technology involved in NAVTEX offers reliable communication for a distance that is significantly beyond simple short-range systems, enabling vessels to stay informed about safety information even at considerable distances from the shore.

In contrast, other choices reflect incorrect assumptions about NAVTEX's capability. Some suggest much shorter or larger ranges that do not align with standard NAVTEX operations. For instance, the day/night variations and line-of-sight limitations described in those options do not accurately represent the communication goals of NAVTEX stations, which are optimized for broader coverage than the limits considered in those alternatives.
