What is the expected range of a VHF radio transmission from a vessel to a shore station?

A About 20 miles
B 50 - 100 miles
C 100 - 150 miles
D 150 - 200 miles
AI Explanation

The correct answer is A) About 20 miles. The expected range of a VHF radio transmission from a vessel to a shore station is typically around 20 miles. This is because VHF radio signals are line-of-sight, meaning they travel in a straight line and are affected by the curvature of the earth and obstacles like land masses. The maximum range is limited by the height of the transmitting and receiving antennas, as well as environmental factors like weather conditions. The other options (B, C, and D) represent ranges that are too long for a typical VHF radio transmission from a vessel to a shore station.
