Hi Jerry,
Since your vertical will not be ground mounted, radials will be even more
important now. You'll want to at least have four radials tuned for a little
over a quarter-wave on the lowest frequency you intend to operate. At
least, this is my best practical advice. Hmmm, I think the ideal is
something like 64 radials tuned for slightly over a quarter wave for each
band... :-)
