Aurora that can reflect VHF signals
Higher signal strength for HF signals passing through the polar regions
Improved HF long path propagation
Reduced long delayed echoes
G3B06: What usually happens to radio waves with frequencies below the Lowest Usable Frequency (LUF)?
They are bent back to the Earth
They pass through the ionosphere
They are completely absorbed by the ionosphere

G3C08: Why are HF scatter signals in the skip zone usually weak?
Only a small part of the signal energy is scattered into the skip zone
Signals are scattered from the magnetosphere which is not a good reflector
Propagation is through ground waves which absorb most of the signal energy
Propagations is through ducts in F region which absorb most of the energy
