Looking at photos from google images CdG seems to have 4 antennae in two pairs. They are horizontal except when the ship is against a pier.
They seem to even be sown while UnRep (Underway Relenishment), which is odd, since you are letting a collision hazard get to 200' of your hull (you really do not want people inside your own turning radius, which, for a carrier is probably 1500 yards).
Fine wire is likely going to be your friend, for being a bit more repeatable than stretched sprue for the length required (from the images, the things are as long as a Mirage). Against that, the prototype antennae are tapered, and visibly so at scale model distances.
