4-way cavity splitter Rangeful CS4W — 4 ports, 50 Ohm

The Rangeful CS4W 4-way cavity splitter evenly divides or combines RF signal power (up to 50 W) between four ports with 50 Ω impedance. Built in a compact aluminum housing with high-quality N-Female connectors, the CS4W is intended for use in cellular amplifier systems, RF distribution and test-bench applications where one input signal must be routed to up to four outputs while maintaining impedance matching and low insertion loss.

Advantages

The CS4W offers a compact, lightweight aluminum enclosure and convenient mounting to surfaces. High-quality N-Female connectors and support across multiple mobile frequency bands ensure reliable connections. Low internal losses and a wide working bandwidth permit higher power operation and consistent port characteristics for multi-line signal routing.

Suitable for

• Splitting a mobile signal to four indoor antennas in buildings
• RF distribution in small broadcast or test setups
• Combining signals in reverse operation as a power combiner (within specifications)
• Use with Rangeful mobile boosters and other 50 Ω cellular equipment

How to use

Connect the single RF source to the input port and attach up to four coaxial cables with N-Male connectors to the output ports. When using fewer than four antennas or outputs, attach a suitable dummy load to each unused port to prevent reflections. Ensure all connections are tightened and the splitter is mounted securely to reduce mechanical stress on cables and connectors. Observe the maximum input power rating and maintain 50 Ω impedance throughout the system.

Usage recommendations

Use the CS4W when you specifically need four output ports; otherwise choose a splitter with fewer ports to reduce attenuation. Verify system impedance is 50 Ω and keep coaxial cable lengths as short as practical to limit additional signal loss. Do not exceed the specified input power and install dummy loads on unused ports.
