The Sennheiser ACA 3 is an active antenna combiner that takes eight antenna inputs down to two outputs (2 x 4:1) at unity gain across 470-798MHz, the rack unit that lets a multi-zone antenna installation feed one receiver system. Switchable 12V DC on every input powers boosters and active antennas, with per-input LEDs for RF, power and overload.
