Which HF bands have segments exclusively allocated to Amateur Extra licensees?
The correct answer is B: 80 meters, 40 meters, 20 meters, and 15 meters. HF bands that have segments exclusively allocated to Amateur Extra licensees are 80 meters, 40 meters, 20 meters, and 15 meters. These four bands have portions reserved for Extra class only, providing additional privileges for the highest license class. For amateur radio operators, understanding these allocations helps explain license class differences and helps ensure legal operation. These are the main HF bands with Extra-only segments.
Exam Tip
Extra-only segments = 80m, 40m, 20m, 15m. Think 'E'xtra = 'E'xclusive segments on 'E'ight, 'F'orty, 'T'wenty, 'F'ifteen meters. These four bands have portions reserved for Extra class only.
Memory Aid
"Extra-only segments = 80m, 40m, 20m, 15m. Think 'E'xtra = 'E'xclusive on 'E'ight, 'F'orty, 'T'wenty, 'F'ifteen. These four bands have portions reserved exclusively for Amateur Extra class."
Real-World Application
Amateur Extra class licensees have exclusive access to certain segments on 80m, 40m, 20m, and 15m. For example, on 20 meters, Extra class has exclusive use of 14.000-14.025 MHz. General class operators cannot use these segments. This provides incentive for upgrading to Extra class.

Why Other Options Are Wrong
Option A: Incorrect. Not all HF bands have Extra-only segments - 160m, 10m, 12m, 17m, 30m, and 60m don't have such segments.
Option C: Incorrect. 160m and 10m don't have Extra-only segments - General class has full access to these bands.
Option D: Incorrect. 60m, 30m, 17m, and 12m don't have Extra-only segments - these bands have different allocation structures.
