The OP should have a look at the coverage maps for Astra 28F on the Lyngsat web site, then make a judgement.
Personally I wouldn't bother with one south of the French Massif Central, and forget about Italy altogether.
Essentially France down as far a Clermont Ferrand (ish), possibly a little farther south in the east, Belgium, Netherlands, and central and southern Germany are about the limit.
