Steve,
Good point. I don't disagree that there are exceptions like this, but
for most paths at most times, low angle paths predominate.
If you study the tutorial I referenced, you'll see that a height between
a quarter wave and 3/8 wave is near ideal for high angle work. That's
130 - 200 ft on 160. Horizontal antennas suffer increasingly greater
ground losses as height is reduced.

As the song goes, “it ain’t necessarily so”. A lot depends upon your ground
conductivity, geomagnetic latitude and what time of night you transmit at.
I have 320 countries worked on 160m from VK6, basically all with ‘low dipoles’ (ranging from 30 to
90 feet in height), mainly worked close to sunrise/sunset (i.e. plus or minus fifteen minutes) when high angle
propagation often dominates over low angle. One of my best contacts with a 45’ high dipole was VP5/WA2VYA,
who was away from the sea and running about 100W to a inverted vee dipole about 15’ high. I was operating
just after my sunset and he was very close to his sunrise – and a solid RST 559.
