What capability does SHF (3 GHz to 30 GHz) provide?

• A. Light anti-jam
• B. World-wide coverage
• C. Poor mobility
• D. No anti-jam features

Answer: (A)

SHF, spanning 3 to 30 GHz, delivers large bandwidth for high data rates, and it does so with very directional, high-gain beams. That directionality lets you concentrate energy along the intended path, which makes it harder for a jammer to disrupt the link unless it specifically targets that beam. In practice, anti-jam capabilities at this band come from these narrow-beam transmissions and the ability to employ frequency agility or spread-spectrum techniques. So SHF provides a light anti-jam capability: it’s not immune to jamming, but the high directivity and bandwidth make anti-jamming more feasible than in lower-frequency bands. World-wide coverage isn’t intrinsic to SHF (it requires satellites or extensive infrastructure), mobility isn’t inherently poor due to the band itself, and there are anti-jam features present, not none.
