Lets way we could build a 5,000 foot tower, nearly a mile high. Such
a tower would have a direct line of sight out to only about 90 miles.
Yes it could transmit to greater distance but that is because the
radio wave bends, either ground waves or by refraction in the
atmosphere. Either way the path length is not predictable. And worse
there is likely some multi path too.
That is one of my projects, I'm slowly building tools to receive WWVB
(60KHz) and compare to "true" time. The goal is to learn something
about the atmosphere from how the propagation delay changes. But I
already know the delay changes and is "noisy"
