Default Angle of radiation

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??. I didnt think the angle would be so great for this antenna.

BTW the antenna was about 30 ft off the ground when in use.
Jimmie
