So 5kHz steps should be "close enough"?

Well I can't use more than 10W anyway, and the only transceiver I have
that does CTCSS has only 5W output.
I wonder if it's worth pointing the 6-element quad at it? I haven't
really used that yet, since I don't have a tower to put it on, and it's
a bit awkward to use hand-held ;-)
