Brad, since you are going to be using fewer than 120 radials, it is
probably not going to be worth your while to cut the radials for
specific bands, that is unless your vertical is mounted up in the air.
If it ground mounted, you can cut the radials to whatever length in
convenient. And the radials do not all have to be the same length.
Again, the only time that cutting the radials to a specific frequency is
warranted is when the vertical is mounted up in the air or when you are
approaching 120 ground mounted radials.
For more info, check out the ARRL Handbook and the ARRL Antenna
Handbook.
