Maritime mobile radio typical use?

Explanation:
Maritime mobile radio is built around line-of-sight, reliable voice communication between ships and shore over typical, near-coast ranges. The VHF marine band (roughly 156–162 MHz) fits this use perfectly: antennas are compact, equipment is robust, and there are standardized channels for everyday ship-to-ship and ship-to-shore traffic, including the distress channel. For long-range communication beyond the horizon, HF is used, but it’s more complex, power-hungry, and less practical for routine on-the-water vocie comm. UHF and SHF serve specialized roles (higher-frequency, line-of-sight links or satellite/radar) and aren’t the standard choice for ordinary maritime mobile communications.
