Cable splitter/combiner Preisner AZ819F

The Preisner AZ819F cable splitter/combiner by Televes is a compact signal distribution device with a silver finish and small footprint (approximately 120 mm × 40 mm × 55 mm). Designed for SAT antenna systems and other RF installations, this unit separates or combines coaxial signals while maintaining low insertion loss and consistent impedance to preserve signal quality across connected devices.

Advantages

The unit offers a compact metal housing in silver that supports reliable thermal dissipation and mechanical durability. Its dimensions make it suitable for installation in tight spaces behind equipment racks or inside wall-mounted enclosures. The design focuses on minimizing signal degradation and maintaining stable connections for multiple downstream devices.

How to use

Install the Preisner AZ819F in line with your coaxial SAT antenna feed or RF cabling. Connect the incoming coaxial cable to the device input and attach the outgoing cables to the splitter/combiner outputs using compatible F-type or specified connectors. Ensure all connections are tightened securely and avoid over-bending coaxial cables near the unit. When combining signals, verify that source levels and impedances are compatible to prevent signal distortion or interference.

Recommendations

Place the device in a ventilated location away from strong electromagnetic interference, and use quality coaxial cables and connectors to preserve signal quality. For complex systems or when combining multiple active sources, consult system diagrams or a qualified technician to ensure correct configuration and impedance matching.
