Splitter Televes AZ417D 4-way 17 dB 5–1218 MHz

Televes AZ417D 4-way 17 dB 5–1218 MHz splitter is a compact RF passive device designed to divide an incoming broadband signal into four outputs while preserving frequency response and providing high isolation between ports. The unit supports a wide frequency range from 5 MHz up to 1218 MHz, making it compatible with terrestrial TV, FM, and many distribution applications. Its 17 dB isolation specification reduces crosstalk between receiver lines and helps maintain predictable signal levels across multiple outputs.

Advantages

The splitter provides consistent performance across the specified frequency band and offers 17 dB isolation to minimise interference between outputs. Its four-output configuration allows a single feed to be distributed to multiple tuners or set-top boxes without active components or power supply. The device is constructed for wall- or cabinet-mounted installation in residential or small commercial systems and is suitable for integration with passive distribution networks and amps where required.

Suitable for

• Distributing a single antenna or cable feed to up to four TV receivers
• Multi-room television setups in homes or small offices
• FM and VHF/UHF signal distribution within residential installations
• Passive splitting ahead of active amplification or signal processing equipment

Key specifications

• Frequency range: 5–1218 MHz
• Number of outputs: 4
• Isolation between outputs: 17 dB
• Passive device: no external power required
• Connector type: F-type compatible coaxial connections (female)
• Typical use: RF signal splitting for TV, FM and broadband distribution

How to use

Connect the incoming RF feed (antenna or cable) to the splitter input and attach coaxial cables from the four outputs to the respective receivers or distribution points. Ensure all connections are tightened to provide good electrical contact and minimise return loss. If the incoming signal level is low, consider placing an amplifier before the splitter or using a dedicated distribution amplifier to compensate for splitting loss. Place the splitter in a dry, ventilated location and avoid exposure to moisture or extreme temperatures.

Recommendations

Verify signal levels at each receiver after installation and use passive splitters only where signal margins permit; when splitting into several outputs or covering long cable runs, use amplification or an active distribution system to maintain service quality.
