MILSTAR operates in which frequency spectrum?

MILSTAR operates in which frequency spectrum?

• A. VHF
• B. SHF
• C. EHF
• D. UHF

Answer: (C)

MILSTAR is designed to provide secure, high-capacity satellite communications, which is best achieved in the Extremely High Frequency band. This spectrum, from about 30 GHz to 300 GHz, offers wide available bandwidth, enabling high data rates necessary for protected military links. The high frequency also allows very narrow, highly directive beams with high-gain antennas, which improves link security by reducing interception and makes the system more resistant to interference and jamming. In contrast, lower-frequency bands have wider beams and limited bandwidth, limiting data throughput and protection levels, so the choice of EHF aligns with MILSTAR’s need for fast, secure, jam-resistant communications.
