What is the frequency for intra Coast Guard communications?

The frequency for intra-Coast Guard communications is identified as CG151, CG401, and CG408. These frequencies are designated specifically for internal communication among Coast Guard personnel, which is crucial for operational coordination and effective communication during missions.

CG151 is used for boat-to-boat communications, facilitating direct contact among units. CG401 serves as a general purpose frequency for communications within the Coast Guard, allowing for a broad range of conversations regarding missions, information sharing, or coordination efforts. Lastly, CG408 is designated for tactical communications, supporting units in the field with real-time coordination needs.

The other options contain frequencies that are either incorrect or do not represent the designated intra-Coast Guard channels. Proper understanding and utilization of these frequencies ensure effective communication, crucial for the successful execution of the Coast Guard's missions.
