What is the frequency range of VHF used for ship-to-ship communications?

Explanation:
VHF encompasses the 30 to 300 MHz range, which is ideal for ship-to-ship communications because signals travel mainly by line of sight and aren’t heavily affected by ionospheric reflection. This makes VHF reliable for short- to medium-range links between ships, using channels typically around the Marine VHF band (roughly 156–162 MHz) within that range. The other options either lie below the VHF band (low-frequency ranges) or above it (UHF and higher), which have different propagation characteristics and use cases. Therefore, the correct frequency range for VHF ship-to-ship communications is 30 MHz to 300 MHz.
