The correct answer is B: 70 centimeters and 13 centimeters. Which UHF amateur bands have frequencies authorized for space stations are 70 centimeters and 13 centimeters. These two UHF bands have space station allocations. For amateur radio operators, this is important for satellite operation. Understanding this helps when working with satellites.
Why Other Answers Are Wrong
Option A: Incorrect. 70 centimeters only isn't complete - 70 cm and 13 cm both have space allocations. Only 70 cm is incomplete. Option C: Incorrect. 70 centimeters and 33 centimeters isn't correct - 70 cm and 13 cm have space allocations, not 33 cm. 33 cm is wrong. Option D: Incorrect. 33 centimeters and 13 centimeters isn't correct - 70 cm and 13 cm have space allocations, not 33 cm. 33 cm is wrong.
Exam Tip
UHF bands with space station allocations = 70 cm and 13 cm. Think 'U'HF 'S'pace = '7'0 cm and '1'3 cm. These two UHF bands have space station allocations. Not only 70 cm, not 33 cm - just 70 cm and 13 cm.
Memory Aid
UHF bands with space station allocations = 70 cm and 13 cm. Think 'U'HF 'S'pace = '7'0 cm and '1'3 cm. These two UHF bands have space station allocations. Important for satellite operation.
Real-World Example
UHF amateur bands with space station allocations: 70 centimeters and 13 centimeters both have frequencies authorized for space stations. Many amateur satellites operate on these bands. The 33-centimeter band doesn't have space allocations. These two bands (70 cm and 13 cm) are the UHF bands with space allocations.
