I've added a relay and extension cord female "pigtail" to my Channelmaster box. I found a 4V coil 10A@125VAC relay from an old computer monitor. And I also found a 5V rail inside the Channelmaster box (which feeds the tuner module inside, and turns off when the remote turns the box "off"), and thru a diode, use to feed the relay. A second diode I strapped across the relay coil to absorb the back EMF. The first diode also helps keep that from getting into the rest of the box as well, and drops the 5V to 4.3V, close enough.

I used double sticky tape to mount the relay, with its terminals pointing up in the air. To keep the powerline away from signals on the circuit board.
