This afternoon while cleaning a closet I pulled out an old US map that
had been marked with contacts I made back when I worked 10M a lot. After
the local stations there is a big empty area on the map then I started
making contacts again at about 300 miles. Antenna used was a 1/4 lambda
groundplane with the radials drooping so to match 50 ohms. A chart I
found indicates that this means I have a vertical angle of radiation of
50 to 60 degrees. Is this correct??.

No, it's not. An antenna doesn't have a single angle of radiation, but
radiates at all angles.

Thanks Roy, I know but the chart I was using wasnt clear on what it was
presenting. It is a photo copied page out of a book and hopefully there was
more info that went with it than what I have. The chart does seem to be
indicating that one should use the closest skip contacts to get an idea of
the radiation angle. It was my doubts about this that inspired my question.
Perhaps I am taking the chart out of context or maybe it is just wrong..
