The same is true of uplinks. SIS Live have a number of dual-dish, dual-redundant uplinks with totally separate power and signal infrastructure allowing them to effectively be two trucks in one. (Though that doesn't cover you if the actual truck is destroyed...)
Or if there's heavy rain over where the truck(s) which will wipe out both. Though I'm sure I remember hearing about a sports event where that happened but one of the uplinks survived because it was via another satellite in the other direction (it's not necessarily rain directly over the dish that's the problem, it's rain in the direction you're pointing)
