The LNB receiver on your satellite dish is a special type of filter that converts the ultra-high frequencies of the satellite's transmissions to a lower frequency that your satellite receiver can use. A coaxial cable, usually RG-6 grade, carries the signal from the LNB to the receiver. Connection is simple and uses standardised connections.
Install an "F-type" connector on the end of your RG-6 coaxial cable. Many RG-6 cables come with an F-type connector pre-installed, so this step is unnecessary if your cable is so equipped. There are different methods of installing F-type connectors, depending upon the brand and model. Follow the manufacturer's instructions.
Locate the F-type output on your LNB. It's usually located on the underside of the LNB, and will be labelled "output."
Line up the F-type connector of your coaxial cable with the output, and gently push it onto the connector. Then turn the nut on the connector to the right to tighten the connection. When the connection is finger-tight, tighten a quarter turn with an adjustable wrench.
Connect the other end of the RG-6 cable to your satellite receiver.
