What band is best suited for communicating via meteor scatter?

Meteor scatter communication relies on radio waves bouncing off the highly ionized trails left behind by meteors as they burn up in the Earth's atmosphere. This propagation mode is most effective in the lower VHF range, specifically between 28 MHz and 148 MHz. Among the choices provided, the 6-meter band (50-54 MHz) is in the optimal 'sweet spot' for meteor scatter. Lower frequencies reflect more easily off these ionized trails and maintain the reflection for a longer duration than higher frequencies. While the 2-meter band (144 MHz) is also frequently used for meteor scatter, 6 meters is generally considered the best suited because the trails remain reflective longer. The UHF and microwave bands (70 cm and 33 cm) are too high in frequency to be reliably reflected by meteor trails.
