Sennheiser AC 41-EU Active Antenna Combiner

Sennheiser's AC-41 antenna combiner lets you connect up to four ew-Series in-ear transmitters to a single antenna and thanks to its active electronics, you can provide each of your SR IEM G4 transmitters with power using the included BNC cable. This not only does away with the need for a bunch of cables, it'll save you a lot of time setting up and an NT 3-1 power supply comes included too.
