Sennheiser ASP 113 Passive 3-Way Antenna Splitter

The ASP 113 is the simple answer to a small rack: one antenna in, three receivers out, no power supply, no settings, nothing to go wrong at 2 a.m. Its 30 to 950 MHz range covers every Sennheiser UHF band and then some, so it stays useful across generations of receivers.

Being passive, it costs signal rather than adding it, which is the tradeoff for its size and reliability. On a short antenna run that is free money; on a long one, put a booster at the antenna first. All connections are BNC, and the 139 x 98 x 53 mm block is small enough to velcro to a rack shelf.
