If you mean DBS band, you strap a DBS LNBF to the side of the feedhorn.

my suggestion would be to purchase a scalar feed with dual lnb set up for prime focus.

the price is 50 + 8 s&h.
if you use a lnb removed from an offset dish, .6 f/d ratio, then you are not getting
a very good illumination of the feed.
the feed i suggested can be adjusted to match your dish f/d ration for max.
illumination.
