The Johansson 4583 is a professional 8-way passive tap for distributing TV and satellite signals from a main trunk line to up to eight outlets simultaneously. With a high tap loss of 25 dB and a frequency range of 5–2300 MHz, it is designed for installations where significant signal isolation between the trunk line and tap outputs is required.

Suitable for indoor use in residential blocks, MDUs and commercial antenna distribution systems, the 4583 features the same robust nickel-plated zinc diecast housing and F-type connectors as the full Johansson 45xx passive tap series.

Key Features

• 8-way passive tap covering 5–2300 MHz (DVB-T/T2, DVB-C, SAT IF)
• High tap loss of 25 dB providing significant signal isolation at tap ports
• Very low through (insertion) loss preserving the main trunk-line signal
• DC power pass for powering active antennas or inline amplifiers
• F-type connectors throughout for secure, interference-free connections
• Nickel-plated zinc diecast housing — compact, durable and easy to install
