As long as they both are powered up, noting much. If one looses power, it *might* try to power up the other one via the antenna feed. With most receivers, even that would likely just be an odd occurrence / no damage caused. The fear is that you have a receiver that *would* be damaged by the back feed. With eight receivers into a coupler, there *could* be quite a bit of current available.
