Which band is best suited for communicating via meteor scatter?

The 6-meter band is particularly well-suited for communication via meteor scatter because of its frequency characteristics and the behavior of meteor trails in the atmosphere. When meteors enter the Earth's atmosphere, they create ionized trails that can reflect radio signals. The 6-meter band, which operates around 50 MHz, is low enough in frequency to benefit from these reflections while still allowing for reasonable path lengths for communication.

At this frequency, signals can maximize the probability of being reflected by meteor trails, especially during meteor showers when these trails are most abundant. The reflections can help facilitate contacts over hundreds of miles, making it ideal for this type of communication.

While the other bands have their uses, they either operate at different frequencies that may not interact as effectively with meteor trails or have limitations related to the typical behavior of scatter at those frequencies. For example, 2 meters and 70 centimeters operate at higher frequencies where the likelihood of effective meteor scatter is reduced compared to the 6-meter band.
