Technician exam question T3C07
Subelement T3, RADIO WAVE PROPAGATION· Group T3C
What band is best suited for communicating via meteor scatter?
- A.33 centimeters
- B.6 meters (correct answer)
- C.2 meters
- D.70 centimeters
Why6 meters is the band best suited for communicating via meteor scatter. Meteor scatter relies on the brief, dense ionization trail a meteor leaves as it burns up in the atmosphere to briefly reflect a signal; 6 meters is the amateur band best suited to this, striking a practical balance between a trail strong enough to reflect the signal and a frequency low enough that the reflection is efficient, answer B. 2 meters (C) and 70 centimeters (D) are used for meteor scatter too but less commonly and effectively than 6 meters, and 33 centimeters (A) is well above the practical range for this mode.
