are the splits to go to different parts of the yard, or to go around an object (like a driveway)? If so, then yu would need an active hub in place of your splitter in your diagram. it safely splts the signal to 2 outputs, and regenerated the signal in case you have long cable runs. whats nice is if you're NOT putting anything else in this area, you can easily use an old atx power suplly you might have laying around to power it. If you MIGHT add some thigs later on, you have powered ssc outputs, AND a DMX output at this location in the yard, sso rather than just splitting, you have options.
