After you have gone through the process of assembling and mounting your satellite dish, the next step is to run the wires from the LNB (Low Noise Blocker), which is the white plastic-capped receiver on the end of the arm extending from the dish, to the receiver inside your home. Being that your dish can also double as a lightning rod and you want to protect your equipment, grounding your system is an important part of the wire install, too.
Find the location where the coaxial cable for your television enters your house. There should be a junction box outside where all the cables for your home converge. If you don't have a junction box, find the cable that leads into your home.
Secure the grounding block. Screw it to the building in a convenient place, close to where your cable enters the house, as well as close to a central grounding point for your home.
Connect an RG6 coaxial cable from your junction box to the grounding block by screwing the male F-connector on one end of your cable over the female F-connection on the junction box. You may need to use a coax cable splitter if you do not have an open female F-connector inside your junction box. If you are replacing the cable television signal with a satellite dish, you might be able to repurpose it as the cable that connects to the satellite dish.
Run a ground wire from the grounding block to your central building grounding location. You can attach the wire to your grounding block by running the wire through the hole for the ground wire, and tightening the screw to secure it.
Run RG6 cable from the junction block to the location of your mounted dish. Screw on the male connector over the female connection in the junction box, and route it up to the dish.
Run the coax cable through the mast of your dish. There is an opening in the mast near the base; push the cable through the mast until it comes out the top.
Take the cable from the top of the mast, and route it through the LNB arm (the arm extending out from the bottom of the dish). Run the cable through the opening on the end of the arm closest to the dish and push it through until it comes out the other end where the LNB is located.
Attach the cable to the LNB (Low Noise Blocker). You do this by screwing on the male connector end of the cable onto the female connection on the LNB.
Affix the LNB to the LNB arm by screwing/bolting it to the extension arm.
It is always recommended to use RG6 coaxial cable with weatherproof shielding any time cable is installed outside.
