Hi, just a quick question I couldn't find answered elsewhere. Does a multicoupler require a power source? I'm looking at, of course, the two Stridsberg active multicouplers on the Scanner Master site. I want to put one in my home, and I am considering one in my car (so when I'm on a "hunt", I can hook multiple scanners up to my mounted antenna). Which is why I'm wondering if the MC requires a power supply, because I don't necessarily have the ability to power it in the car.
