In which frequency bands can the ARC210 operate?

The ARC210 is a versatile communications radio that operates across specific frequency bands suitable for military communication. The correct choice reflects that it can effectively operate in UHF (Ultra High Frequency) and VHF (Very High Frequency) bands, as well as utilizing FM (Frequency Modulation) for some of its communication capabilities.

This functionality allows for secure and reliable voice and data transmissions in various operational environments, making it an essential tool for tactical communications. The inclusion of FM alongside UHF and VHF highlights its adaptability, especially in environments where clear audio quality is necessary.

The other options do not accurately represent the ARC210's capabilities. For instance, while HF (High Frequency) is significant for long-range communications, it is not part of the ARC210's operational bands. Additionally, the reference to specific modulation techniques like AM (Amplitude Modulation) in one of the other options does not align with the known operational characteristics of the ARC210. Thus, the selection accurately captures the radio's purpose and deployment context.
