Hmm... a quick search for 110BS gave me this datasheet:
http://www.sesl-sharp.com/Products/pdf/rf201309_e.pdf
Frequencies there are a little broader. If this datasheet is
right, .freqrange should be:

I don't like the idea of using an index here. It would be easy
to have this broken.
Also, probably the best would be to add another field and/or a libdvbv5
property to indicate the DiSEqC specific stuff as found in Japan.
What kind of DiSEqC switch are you using (if any)?

Are you sure that this need is due to ISDB-S, and not due to a
different DiSEqC switch or satellite system arrangement?
