No, jth877, my information is correct - you are incorrect, and I will prove it.
First, let's look at a Model 60 antenna coil as shown on a Model 60 schematic.

I have numbered each terminal of this coil on the partial schematic above. Notice there not only is a winding between lugs 2 and 5, but if there were no windings between those two lugs, the set would not play unless someone connected the lead to the tuning condenser and 6A7 control grid to lug 2 instead of lug 5. And then, its performance would be iffy at best.
To reinforce this thought, here is a crude illustration of the bottom view of a Philco model 60 antenna coil.

Looking at the bottom side of the coil, where the lugs and mounting bracket are, you count the lugs clockwise starting at the first lug to the left of the mounting bracket, as shown above.
"Top" is a terminal on the very top of the antenna coil, not shown in this crude illustration.
"GND" is the mounting bracket itself, which also has a lug connected to it. The coil will be grounded by the mounting lug and the bolt which secures it to the chassis (ground).
