The Johansson 4544 is a TAP-type signal distributor with one input and four outputs, operating across the 5–2300 MHz frequency range. It includes DC pass support and features a 30 dB insertion loss — the highest tap value in the Johansson 454x series — making it the correct choice for tap points located close to the signal source, where trunk signal levels are highest.

This unit is designed for professional antenna distribution infrastructures such as apartment blocks, hotels, and commercial buildings, where a cascaded tap system is used to serve multiple subscriber outlets from a single trunk line.

Key Features

• TAP configuration: 1 input, 4 outputs
• Broad frequency range: 5–2300 MHz
• DC pass on input
• Insertion loss: 30 dB
• Port isolation: 25 dB
• Return loss (input/output): 10 dB

Product Benefits

• 30 dB tap loss is suited for near-source tap positions where the trunk signal is at its strongest
• 25 dB port isolation limits inter-outlet signal interference within the subscriber network
• Full 5–2300 MHz coverage spans terrestrial, satellite IF, and DOCSIS upstream bands
• DC pass supports powering of active upstream components without dedicated power cabling
