How to use
Mount the Kathrein KEL 411 on the feed arm of a compatible parabolic dish so that the 4 cm feedhorn is correctly positioned at the dish focal point. Connect the F-type RF connector to the coaxial cable leading to the satellite receiver or multiswitch. Ensure the receiver provides the required power via the coaxial cable and configure the receiver to the satellite frequency range of 10.7–12.75 GHz. Fine-tune dish alignment while monitoring signal strength on the receiver to achieve optimal reception.
Usage recommendations
Use weatherproof F-type connectors and properly seal cable joints when installing the LNB outdoors. Verify that the dish size and focal position are appropriate for a 4 cm feedhorn to maintain signal quality. For multi-tuner systems, confirm that the receiver or multiswitch supplies sufficient current and compatible polarization switching methods.
