4-way splitter Televes AZ48TD 5–1218 MHz, 8 dB attenuation

Televes AZ48TD is a 4-way RF splitter designed to distribute a single RF input into four matched outputs across the 5–1218 MHz frequency band. The device provides 8 dB port attenuation so each output receives an even, predictable level while preserving impedance matching to minimise reflections and signal loss. The compact metal housing and F-type connectors make it compatible with terrestrial TV, CATV and other RF distribution systems requiring stable multi-output splitting.

Advantages

The splitter delivers uniform signal division with fixed 8 dB attenuation on each output, facilitating balanced feed to multiple receivers or amplifiers. Its frequency coverage from 5 to 1218 MHz accommodates VHF, UHF and many CATV channels. The robust housing and standard connectors ensure reliable mechanical and electrical connections, while the matched impedance reduces the need for additional matching components.

Suitable for

• Terrestrial TV distribution to multiple receivers
• Cable TV (CATV) systems requiring even signal split
• RF test setups that need four matched outputs
• Shared antenna installations in residential or light-commercial premises

Key specifications

• Frequency range: 5–1218 MHz
• Number of outputs: 4
• Port attenuation: 8 dB per output
• Connector type: F-type (female)
• Impedance: 75 ohm matched
• Housing: metal chassis for shielding and durability

How to use

Connect the incoming RF feed (antenna or cable) to the splitter input connector and attach the four output ports to downstream receivers, amplifiers or distribution cables using appropriate 75 ohm coaxial cables with F-type connectors. Ensure all connections are tightened to provide secure electrical contact and minimise insertion loss. Place the splitter in a ventilated, dry location and avoid exposure to direct moisture. If signal levels appear low, verify upstream signal strength and cable quality before adding amplification.

Recommendations

For optimal performance, use short, high-quality 75 ohm coaxial cables and keep cable runs as symmetrical as possible. When splitting signals to multiple rooms or long cable runs, consider the cumulative attenuation and, if necessary, use a line amplifier or active distribution device placed before the splitter to compensate for the 8 dB output loss.
