Splitter Televes AZ28D 2-way 5–1218 MHz, 8 dB insertion loss

Televes AZ28D is a compact 2-way RF splitter that distributes a single coaxial feed into two outputs across the 5–1218 MHz frequency range. Designed for indoor installations in residential and commercial TV and radio distribution systems, the splitter features a defined frequency response and an 8 dB insertion loss per output. Its robust housing and impedance-matching design maintain signal integrity when integrating into headends, amplifier chains, or simple distribution networks.

Advantages

The splitter offers a consistent 5–1218 MHz bandwidth and predictable 8 dB insertion loss, which simplifies system planning and link-budget calculations. Its two-output architecture allows easy splitting of terrestrial TV, FM radio and other RF services without requiring active electronics at the split point. The compact form factor supports indoor mounting and straightforward integration with standard coaxial connectors and passive distribution components.

Suitable for

• Domestic TV and FM radio distribution to two receivers
• Small headends and multiswitch systems requiring passive splitting
• Connection between an antenna or amplifier and two downstream devices
• Temporary signal distribution for testing and maintenance

Key specifications

• Frequency range: 5–1218 MHz
• Number of outputs: 2
• Nominal insertion loss: 8 dB per output
• Impedance: 75 ohm
• Application: passive RF splitting for TV and radio signals
• Mounting: indoor, compact enclosure

How to use

Connect the incoming coaxial feed to the splitter’s input and run two coaxial cables from the outputs to the downstream receivers or amplifiers. Ensure all connectors are properly tightened and use 75 ohm coaxial cable throughout the link to maintain impedance matching. When used in conjunction with amplifiers or active components, account for the 8 dB insertion loss per output when setting amplifier gain to avoid overload or insufficient signal levels. Position the splitter in a dry, ventilated indoor location and avoid placing it near strong heat sources or high-interference equipment.

Recommendations

For longer cable runs or systems with low input levels, consider using a low-noise amplifier before the splitter to compensate for the insertion loss. Verify signal levels at each receiver after installation and apply additional amplification or attenuation as needed to achieve optimal reception.
