Sennheiser ACA 3 Dual-Channel 4:1 Antenna Combiner for Wireless Receivers (470 to 798 MHz)
Expand your wireless coverage with the Sennheiser ACA 3, a dual-channel 4:1 antenna combiner compatible with all stationary Sennheiser analog and digital receivers. Well suited for use in larger venues, houses of worship, and broadcast installations with distributed antenna systems, each channel of the unit allows you to combine and distribute the RF signal from up to four connected antennas to a receiver. The front panel offers switchable DC power controls for the eight BNC inputs (four for each receiver) for active antennas or head amps. The RF signal from each antenna input can also be switched off independently, allowing you easily isolate unused antennas.
