Rated 4.0 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by This solved an intermittent problem. I have had the X10 or equivalent equipment in my home for 25 years. Most of the time is works well but it also fails. A light will not turn on or sometimes turns on but not off. I tried a capacitor type phase coupler but it burned out quickly. Not sure that it worked at all, it may have burned out in just days after installation. I tried the expensive signal booster with no apparent improvement. So now I have a Smarthome Signa Linc Phase Coupler hardwired into the breaker panel. I bought two intending to install the second one in a detached garage that has 140 feet of wire to it from the house. I also have a boat dock with 370 feet of wire to it from the house. This Phase Coupler solved the problem even without installing the second one. I have had reliable switching to the garage and boat dock for two months now. April 13, 2012
