The Johansson 4543 is a TAP-type signal distributor with one input and four outputs, operating across the 5–2300 MHz frequency range. It supports DC pass and delivers 25 dB insertion loss, making it appropriate for tap points further along a distribution cascade where a higher tap loss is needed to maintain trunk signal levels.

Designed for professional antenna distribution networks, this unit allows a main coaxial trunk to feed multiple subscriber outlets while keeping the trunk signal intact for downstream devices.

Key Features

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

Product Benefits

• 25 dB tap loss suits mid-to-far positions in a cascaded distribution system where trunk signal is stronger
• 25 dB port isolation effectively prevents signal leakage between subscriber outputs
• Wide frequency range accommodates terrestrial, satellite, and cable signals simultaneously
• DC pass enables powering of active antenna components without extra cabling runs
