Question
Which UHF amateur bands have frequencies authorized for space stations?
Answer Options
- A) 70 centimeters only
- B) 70 centimeters and 13 centimeters
- C) 70 centimeters and 33 centimeters
- D) 33 centimeters and 13 centimeters
Correct Answer: B
Explanation
The UHF (Ultra High Frequency) bands are widely used for amateur satellite communication, offering sufficient bandwidth for high-speed data and efficient antenna systems. Similar to the VHF and HF bands, specific amateur UHF bands are allocated for space stations to ensure compatibility and non-interference.
The authorized UHF amateur bands with frequencies for space stations are the 70 centimeters (420-450 MHz) and 13 centimeters (2300-2450 MHz) bands. These bands are commonly used for satellite uplinks and downlinks, with the 13cm band (S-band) often used for high-speed digital communications or downlink telemetry from advanced amateur satellites.
