What band is best suited for communicating via meteor scatter?

Meteor scatter propagation relies on the brief, highly ionized trails left behind by meteors burning up in the Earth's upper atmosphere. These temporary ionized trails act like fast-fading reflectors for radio waves. Among the amateur bands, the 6-meter band (around 50 MHz) is universally recognized as the best suited and most consistently used for meteor scatter. The physics of these ion trails reflect frequencies around 50 MHz much more effectively and for longer durations than higher frequencies. While the 2-meter band can also be used for meteor scatter, the duration and strength of the reflections are significantly weaker. Higher frequency UHF bands like 70 centimeters and 33 centimeters are generally ineffective for this mode.
