Yes. It came with the version of the antenna I ordered (#
308433), but if you order just the
antenna, it is also available on the Wilson website - A Wilson Electronics 3 way mount (
#901104). You will also need an adapter to connect the antenna to the Sleek -
Wilson #971119.
Again, I'm not saying you will need the Sleek & outside antenna, but if you plan to get off the beaten path, together they will often give you a useable signal where the phone alone won't.
