I see an interest in having a ground plane antenna for two bands.  This is
possible by changing the length of two opposing radials as detailed in the
following article.

A 10 meter GP can also be tuned for 10 and 12 meters.  Or a 12 meter GP can
be tuned to both 15 and 10 meters by making one radial pair longer and the
other pair shorter.

The following link on elevated radials should give what you need to know
about length of the vertical monopole and the length and angles of 2, 3, 4,
6 or 8 radials.
