Can I use the Ultra Mini 2 (CM3412) distribution amplifier with both my antenna and my cable TV at the same time?
No, the Ultra Mini 2 (CM3412) cannot be used with both the antenna and cable TV at the same time. If you need to get both over-the-air and cable TV signals to the TV at the same time, it will be necessary to run two separate cables, one from the antenna and one from the cable TV system. Then install a coax switch behind your TV.
