Hard, perhaps; impossible, no.
a) strip jacket back about 3/4", unravel braid, separating the center conductor, and retwist braid into a seperate single "wire". Strip center conductor as required and terminate both.
b) Strip jacket and braid back by about an inch. Strip jacket back a bit further, leaving braid exposed. Take a small piece of wire, strip back 1/2", form a noose and solder it around exposed braid. Treat remainder as 2 separate wires.
You could also go with something like a BNC connector, but they're a pain in the butt to deal with.
