Lets assume a single hop 40m signal from 400 miles away. What
elevation angle does it arrive at? Both stations are using inverted V's
at nominal height. There are no large bodies of water in between.

Daytime and/or nighttime.

depends on the height of the reflecting/refracting layer, time of day,
sunspot number and associated geometry. Intensity of signals will depend on
how the radiation angle - pattern of the antennas fits the propagation
angles.
There are some propagation programs that will provide good answers based on
above data.
