Varies by the station & group. Some have fully redundant EVERYTHING... two transmitters, two antennas, two sources to the transmitter, etc. One station I had visited had two generators, each capable of powering the studio building. "Why two?" we asked. "In case the first one fails." That seems over kill to me.Redundancy?!?! Ha! That went away at my last station with the digital switch. They didn't want to spend the money. So when our network last had the Super Bowl, which of course is a HIGH REVENUE program, they brought in a Live Truck operator to establish a microwave shot from the station to the transmitter, and had an engineer at the transmitter so that if something happened to the fixed link to the transmitter, they could switch to the Live Truck signal.
That station didn't even upgrade their backup transmitter to digital because "the main transmitter will never go down and besides nobody watched over the air anymore anyway" Boy, has that changed in recent years as people cut the cord. The main transmitter is at the site of our 2,000 foot tower. They still are part owners of the old 1,500 foot tower but do not keep a transmitter there.
Redundancy is nothing more than insurance. You hope you never need it, but when you do, it can save you a lot of money.
