The Johansson 9609 is an adjustable in-line attenuator for terrestrial and satellite signal distribution systems. Its attenuation is manually variable from 0 to 20 dB, allowing precise level adjustment at any point in a coaxial distribution network without the need to replace fixed attenuator pads.

The compact 77 × 22 × 17 mm body and DC power pass capability make it practical for installations where space is limited or where the attenuator must be inserted in a line that carries DC power to an LNB or amplifier.

Key Features

• Adjustable attenuation: 0–20 dB, continuously variable
• Frequency range: 700–2150 MHz
• DC power pass: yes
• Dimensions: 77 × 22 × 17 mm

Product Benefits

• Variable attenuation eliminates the need to stock multiple fixed attenuator values — one unit covers the full 0–20 dB range
• DC pass allows the device to be placed in-line on a satellite feed without blocking power to the LNB
• 700–2150 MHz coverage spans both the UHF terrestrial band and the full satellite IF band
