Which VHF amateur bands have frequencies authorized for space stations?
The correct answer is D: 2 meters. Which VHF amateur bands have frequencies authorized for space stations is 2 meters. Only the 2-meter band has space station allocations in VHF. For amateur radio operators, this is important for satellite operation. Understanding this helps when working with satellites.
Exam Tip
VHF bands with space station allocations = 2 meters only. Think 'V'HF 'S'pace = '2' meters. Only the 2-meter band has space station allocations in VHF. Not 6m, not 1.25m - just 2 meters.

Real-World Application
VHF amateur bands: Only the 2-meter band has frequencies authorized for space stations. The 6-meter and 1.25-meter bands don't have space station allocations. Many amateur satellites operate on 2 meters (uplink or downlink). This is the VHF band with space allocations - 2 meters only.
