    These are apparently Rohr's effort to make horn antennas for the Bell System. These were an artifact of five nines reliability. Most of the 3500-4000 MHz links these carried have been transitioned to (reliable) fiber.

    In a WalMart culture, where everyone is trying to get something for nothing, there's no room for five nines reliability.
