Sennheiser ASP 114 Passive 4-Way Antenna Splitter

The ASP 114 splits a single antenna four ways for a rack of non-diversity receivers, or feeds four A inputs from one shared element. It is entirely passive, so there is no supply to lose and no amplifier to overload, and it lives in the same 139 x 98 x 53 mm housing as the rest of the ASP family.

Use it where the antenna run is short and the loss budget can absorb a passive split. Where the cable is long, put gain at the antenna end first with a booster, then split. For a two-antenna true-diversity rack the ASP 212 is the matching part, splitting an A and a B feed two ways each.
