Older MH's had a separate switch hidden somewhere for power to the over the air antenna. The Entegra BOMB gets power to the antenna with power from the BOMB. Nice part about the Entegra BOMB, you don't have to worry about turning off the hidden antenna switch to scan cable channels....just hit the button for cable it automatic. On my previous MH I use to forget that all the time! It was a pain, it was a button part of a 12v outlet.
