## Long description

The Kathrein KEL 422 is a low noise block downconverter (LNB) designed for satellite signal reception in the 10.7–12.75 GHz frequency range. The unit provides reliable frequency conversion and a stable RF output via an F-type connector. Compact in size with a 4 cm feedhorn diameter and modest power consumption of 125 mA, the KEL 422 is intended for installations where space efficiency and low power draw are priorities. The housing is finished in white and the overall dimensions support mounting on a variety of small to medium satellite reflectors.
Advantages
The KEL 422 combines low-noise performance with a compact mechanical design, enabling good sensitivity without occupying excessive space on the dish. Its standard F-type RF connector ensures wide compatibility with satellite receivers and cabling. Low current consumption reduces load on power supplies and multiswitch systems. The white finish and small footprint simplify integration into residential or commercial installations where appearance and unobtrusive mounting matter.
Suitable for
Single-dwelling satellite reception with compact parabolic dishes
Small commercial installations requiring low-power LNBs
Replacement of similarly sized LNBs on Ku-band dishes
Setups where a standard F-type connector is required
Key specifications
Frequency range: 10.7–12.75 GHz
Feedhorn diameter: 4 cm
RF connector type: F
Power consumption: 125 mA
Dimensions (approx.): 131 mm width × 108 mm depth
Finish: white
Packaged weight: 340 g
How to use
Mount the LNB onto a compatible feed arm or bracket of a parabolic satellite dish, ensuring the 4 cm feedhorn is correctly aligned with the dish focal point. Connect the RF cable with an F-type connector to the LNB output and route the cable to the satellite receiver. Power for the LNB is supplied through the receiver or an external power inserter; verify that the supply can deliver the nominal current. Fine-tune dish pointing while monitoring signal strength and quality on the receiver until optimal reception is achieved.
Usage recommendations
Use weatherproof F-type connectors and appropriate sealing at the cable entry points to protect against moisture. When replacing an existing LNB, confirm the mechanical fit and focal offset to match the new feedhorn diameter for best performance. For multi-tenant or multi-receiver systems, consult compatibility requirements for power distribution and potential need for multiswitches or separate LNBs.
