This ANGUS (Acoustically Navigated Geological Underwater Survey) image is one of only a handful that show surviving antenna fittings at the time of Titanic’s discovery. The view is straight down, basically over the Silent Room. Farthest to port is a vent with what may be a butterfly valve inside, presumably to vent the warm Silent Room. Next to that is a flat, circular object or "stain." Inboard of those is a cast-iron roof gland from which a bent section of connecting rod for the Bradfield insulator protrudes. The gland is surrounded by what appears to be a square line of caulking that once sealed the base of the aerial trunk upon which the lead-in insulator was elevated.
