Pru stopped broadcasting when JHC went onling in the 60's. By then some areas south of the JHC where getting signal issues caused by radio beams reflecting off the Hancock tower and arriving at people's receivers a split second after the waves direct from Pru. This would cause double images.

The antenna is a large, structurally integrated part of the building. Removing it would have been very expensive.
