My spin -- comments welcome

Are you talking about the antipode distance or how far a radio wave can
travel around the earth ???

For antipode -- The earth has a circumference of approximately 24,900 miles.
More precisely the circumference of the earth at the equator is 24,902 mi
So 1/2 of 24,902 = 12,451 miles. That's half way around the world (at the
equator)
But as some one quipped -- from you to your next door neighbor is all the
way around the earth ~ 24,900 miles

For radio transmissions, one can transmit long path and achieve distances
greater than 12,451miles

For example the short path distance from So Calif to South Africa is about
9,895 miles but the long path distance is 14,962 miles

I have worked long path to South Africa on Ham radio many times

Just curious. Anyone know what the longest GC distance from any point on
Earth to any other point?
