Simple 2 m 1/4 wave groundplane radial angles?

[James2]

I am building a simple 2 m 1/4 wave groundplane antenna consisting of five brass rods, one 19.5 to 20 inch vertical soldered to an SO-239 connector and four 19 inch radials bolted to the connector holes of the SO-239.

My question is "what angle should the radials be set at?" The picture shows them at 45 degrees, I think, but I have seen other antennas with radials at 60 degrees or even 80 degrees.

................Cut four pieces, 19 inches long for the radials. On one end twist the rod to form a loop. Fasten the radials to the chassis connector holes by running the four small bolts through the loops and bolt on the other side. Note :If you have access to an SWR meter, you can cut the center element at 20 inches and then prune the element ( about 1/8 " at a time ) for best SWR.
