The negatives first: The connecting wires are too short and are supplied untinned - so you can not easily be incorporated into an e-distribution the phase coupler. At least one tinning would be appropriate manufacturer.
The Positive: In addition to building - Cable route: 70 m between buildings + 20 m inside the outbuilding (after a sub-distribution in NG now work after installation of the phase coupler both LAN and WLAN - Peformance 15-30 Mbit / s it. a slight slowdown in WG verschmerzbare with us on the stage of the dLAN "feed" on the router by approximately 20% (decrease of 90 Mbit / s to 75 Mbit / s) was observed.
Conclusion: It is the success of a phase coupler mE not predict with certainty, because the installation topologies can be very different but - in our case it worked well and was (is) worth the try.
