The Johansson 9671L is a combined TV-SAT line amplifier designed to boost both terrestrial (UHF/VHF) and satellite IF signals on a single device. It has one input and one output, and includes a built-in LTE/4G filter that suppresses interference from mobile networks in the 790 MHz and above band, protecting the terrestrial reception path without requiring a separate filter.

Gain is adjustable on the terrestrial path (7–27 dB) while the satellite path features a fixed 8 dB slope. A switchable DC power pass function allows the unit to supply voltage to upstream LNBs or other devices via the coaxial input. Power is supplied from the mains via a universal 85–240 V AC input.

Key Features

• 1 input / 1 output configuration
• Built-in LTE/4G filter for terrestrial path interference rejection
• Adjustable terrestrial gain: 7–27 dB
• Adjustable satellite gain: 12–32 dB
• Fixed satellite slope: 8 dB
• Switchable DC power pass (output to input)
• Universal mains input: 85–240 V AC, 50–60 Hz

Product Benefits

• Combined TV+SAT amplification in a single unit reduces the number of devices in the installation
• Built-in LTE/4G filter eliminates the need for a separate 4G interference filter in the signal chain
• Adjustable gain on the terrestrial path allows the amplification to be tuned to the actual received signal level
• Switchable DC pass lets the amplifier power a connected LNB through the coaxial cable

Why You'll Love It

• Single-box TV+SAT solution keeps the installation tidy and the component count low
• Universal 85–240 V input works anywhere in Europe without an adapter
• The LTE/4G filter is built in, so there is one less component to source and install
• Adjustable gain means the amplifier can be set correctly for the signal level at the installation point
