 Your imaginings are consistent with my memory.
 The radiator, about a 24 inch face stick, maybe 36, had an 18 inch
 or so "cable race" tower next to it, about two feet away,
 bonded at its top to the taller radiator stick. 
 Cables were run up in standard fashion for any grounded tower, except
 they ran up the smaller "race" tower.
 I didn't climb it, but presume that *all* were bonded at the point where
 the bridge ran from the larger to the smaller steel.
 That bridge appeared to be a short section of the smaller tower.
 As I recall, it was pretty heavily loaded.

 Another "odd" feed, though it's been some years since I was there,
 is/was the 1100 Cleveland.  ( WTAM/WKYC/WWWE/KYW )
 1/2 wave radiator fed at the base through a 1/4 wave section of
 tower layed horizontally and supported just above ground.
 Can't remember much more than that, though.
 RAM needs a refresh cycle, I guess.
