It makes sense that it was only on 3 window per side 741s since their upper decks were often lounges, so any extra space at the end of the upper deck needed for the new installation wouldn't really be missed much. They could "tap into" the rear of the upper deck for that antenna bubble and really not impact lounge operations. When they started using the upper deck for regular seating it went away, either because it didn't work well, wasn't needed, or the airlines decided that they wanted whatever space was being occupied by the installation for one or two last rows of seats. Anyway, that's my interpretation worth exactly a plug nickel in inflation adjusted dollars!
