Chart in my 1994 edition ARRL antenna handbook says the optimum angle
varies with the the wave angle. Between 52 degrees for zero wave angle
to 60 degrees for 30 degree wave angle. That's the tilt angle, the angle
between the wires and the line between the side supports. So half the
angle at the feed would be 90 - 52 to 60 or 30 to 38 degrees, V angle at
the feed line then would be 60 to 76 degrees depending on the desired
wave angle. I'd shoot for 15 or 20 degrees wave angle which calls for
tilt angle of 53 to 55 degrees or 35 to 38 half angle at the V or 70 to
76 degrees at the feed.
