Which band is commonly referred to as a "narrowband" in satellite communications?

• A. SHF
• B. EHF
• C. UHF
• D. VHF

Answer: (C)

The UHF band is commonly referred to as a "narrowband" in satellite communications because of its frequency range, which allows for tightly packed channels that can be used for specific applications like voice communication and telemetry. UHF operates between 300 MHz and 3 GHz, and its nature supports the transmission of data at lower bandwidths, which is characteristic of narrowband systems. In satellite communications, narrowband signals are particularly advantageous for certain types of data transmission where bandwidth efficiency is critical, such as in military operations or remote communications. The other bands mentioned, such as SHF, EHF, and VHF, typically support wider bandwidths and are used for different types of communications requirements and applications. Understanding the specific characteristics and uses of different bands is essential for effective utilization in various communication contexts within the space domain.
