The Johansson 9720 Wideband LNB receives any standard Ku-band satellite signal and converts it into a single output frequency range of 290–2340 MHz. It produces two outputs — one Horizontal and one Vertical — each containing both the low and high band of the respective polarisation, eliminating the need for a traditional quad LNB and separate switching electronics.

Designed for professional satellite distribution systems, the 9720 reduces the number of cables and connections required at each satellite outlet, cutting installation time and long-term maintenance costs.

Key Features

• Single Ku-band input (1 orbital slot), two IF outputs: Horizontal and Vertical
• Each output carries both low and high band of its polarisation (290–2340 MHz)
• LO frequency of 10410 MHz with typical conversion gain of 55 dB
• Ultra-low noise figure of 0.5 dB (typical)
• Cross-polarisation isolation of 25 dB
• Power consumption under 1 W — reduces load across the entire distribution chain
• Standard 40 mm LNB mount fitting

Product Benefits

• Fewer cables needed per dish position lowers installation cost
• Fewer connections in the signal path means a more reliable system overall
• Lower power draw reduces heat in headend and amplifier equipment
• Compatible with distribution amplifiers and multiswitch systems designed for wideband signals
