Some information came to light today on the 22-23 series?? or at least the 49 vacuum antenna setup. It is slightly different than the 47.

Instead of vacuum source being directly off the manifold as it appears to be in 47, it seems in later cars they used the same vacuum source for the antenna as was used for the windshield wiper motor.

There was a tee added in the short hose just before the motor. From that tee a hose went over and into the end firewall grommet along with the two tubes which exit to antenna. The 49 grommet has 3 vacuum tube holes on the top similar to 47's two. There is a 4th hole for the antenna lead in wire on the bottom of the grommet.
