The Johansson 4522 is a TAP-type coaxial distribution component with 1 input and 2 tap outputs. At 20 dB insertion loss and 30 dB port isolation, it is designed for use at later stages of a distribution cascade, providing two subscriber drops where residual signal levels can support a higher tap extraction value.

DC pass capability lets supply voltage travel through the coaxial cable, enabling direct powering of active antenna components such as masthead amplifiers or LNBs without a separate supply run.

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: 20 dB
• Isolation between output ports: 30 dB
• Return loss on input and output: 10 dB

Product Benefits

• 20 dB tap value fits positions further down a distribution cascade where earlier taps have reduced the trunk signal level
• 30 dB isolation provides effective separation between the two tap outputs and the through path
• Two simultaneous outputs serve dual subscriber drops from a single component, avoiding a separate downstream splitter
• Wide 5–2300 MHz bandwidth handles all standard broadcast, satellite, and broadband frequencies in one passive unit

Why You'll Love It

• Sits between the 4521 (15 dB) and 4523 (25 dB) in the Johansson 452x series, completing the range for precise cascade budget design
• The 30 dB isolation matches the higher-loss models in the series, maintaining consistent port separation across the product line
• Two outputs mean a single component handles a dual-subscriber tap point in deeper cascade positions
• DC pass maintains the active antenna power path through the unit without any extra hardware
