The actual work took place on Crawford Hill, which is not located near the main Bell Labs complex, which was known to the local engineers as the "Black Box" facility.
Crawford Hill, and the Horn Antenna and the building where my father worked and where Bob worked is at 791 Holmdel Rd, Holmdel NJ. I just checked the Google Map for that area and I still see the Horn Antenna in the photo. Unfortunately there is no date on the photo. But it looks fairly recent. Maybe the antenna is still there and DNA Thumbs is simply looking in the wrong spot.
If I want to find out for sure I could Email Bob, I'm sure he would know if it's been removed for some reason.
