The Johansson 4523 is a TAP-type coaxial distribution component with 1 input and 2 tap outputs. With 25 dB insertion loss and 30 dB port isolation, it provides the deepest tap value in the Johansson two-output TAP series, making it appropriate for the final dual subscriber connection on a long distribution run.

DC pass capability lets voltage pass through the coaxial cable to power active components — such as masthead amplifiers or LNBs — without a separate power feed on the same line.

Key Features

• TAP configuration: 1 input, 2 outputs
• Frequency range: 5–2300 MHz, covering terrestrial, satellite, and DOCSIS bands
• DC pass on the input port
• Insertion loss: 25 dB
• Isolation between output ports: 30 dB
• Return loss on input and output: 10 dB

Product Benefits

• 25 dB tap value suits the final dual-drop positions at the end of a cascade where earlier taps have consumed the majority of the signal budget
• 30 dB isolation provides strong port-to-port separation across both tap outputs and the through path
• Two outputs serve a dual subscriber point in a single component, eliminating the need for a separate downstream splitter
• Wide 5–2300 MHz bandwidth covers terrestrial, satellite, and broadband frequencies without additional filtering

Why You'll Love It

• Completes the Johansson 452x dual-output TAP series alongside the 10, 15, and 20 dB models, enabling precise signal budget planning across the cascade
• 30 dB isolation matches the other high-loss models in the 452x range, ensuring consistent port separation across the entire distribution system
• Single component replaces a tap plus a two-way splitter for the final dual-subscriber position
• Full 5–2300 MHz coverage means one component handles both terrestrial and satellite signals at the end of the line
