The Johansson 4582 is a professional 8-way passive tap for distributing TV and satellite signals from a main trunk line to up to eight separate outlets simultaneously. With a tap loss of 20 dB and a frequency range of 5–2300 MHz, it is suited to installations where a higher tap attenuation is needed to balance signal levels across a larger distribution network.

Designed for indoor installation in residential blocks, MDUs and commercial antenna systems, the 4582 shares the same compact nickel-plated zinc diecast housing and F-type connector standard as the full Johansson 45xx tap series.

Key Features

• 8-way passive tap covering 5–2300 MHz (DVB-T/T2, DVB-C, SAT IF)
• Tap loss 20 dB for controlled, predictable signal distribution
• Low through (insertion) loss preserving signal on the main trunk line
• DC power pass for powering active antennas or inline amplifiers
• F-type connectors throughout for reliable, interference-free connections
• Nickel-plated zinc diecast housing — compact and durable

Product Benefits

• Higher 20 dB tap attenuation ideal for closer tap-offs from high-level distribution lines
• 8 simultaneous output ports support multi-room or multi-flat installations from one cable run
• Low trunk-line through loss keeps the main signal intact for further cascade taps
• Consistent build quality across the 45xx series simplifies mixed-tap installations
• Professional Johansson reliability for long-term, maintenance-free performance
