The Johansson 9674L is a combined TV and satellite line amplifier designed for residential and small installation use. It accepts a single input carrying both terrestrial TV (47–790 MHz) and satellite IF signals (950–2150 MHz), amplifies both bands, and distributes the amplified signal to four outputs. The built-in LTE/4G filter blocks interference from 4G mobile signals before they reach connected televisions or satellite receivers.

Terrestrial gain is adjustable from 0 to 18 dB, while satellite gain is adjustable from 2 to 22 dB, with a fixed 8 dB slope on the satellite band for cable compensation. DC power pass to the LNB is switchable, and the unit accepts universal mains voltage from 85 to 240 V AC.

Key Features

• 1 input / 4 outputs for distributing one aerial/satellite feed to four TV points.
• Built-in LTE/4G filter removes interference from 4G mobile networks.
• Adjustable gain: 0–18 dB (terrestrial) and 2–22 dB (satellite).
• Fixed 8 dB slope on the satellite band for cable loss compensation.
• Switchable DC power pass (output to input) for powering an LNB.
• Universal mains input: 85–240 V AC.

Product Benefits

• One amplifier feeds four TV or satellite points — replaces a passive splitter that reduces signal level.
• The LTE/4G filter prevents picture breakup caused by local 4G transmitters.
• Adjustable gain compensates for different cable lengths or signal conditions at the installation site.
• Switchable DC pass allows the amplifier to power a satellite LNB through the coaxial cable without a separate power supply.
• Universal mains input makes it suitable across European voltage standards without adaptation.
