I just mounted my satellite dish on my roof. How can I prevent lightning from causing any damage to it? I'm always worried a bit when storm comes. I can only disconnect the cables from the receivers, but I can't do anything with the LNB. I don't want to call a professional, just want to create my own simple lightning rod. It would be placed near my dish.

Is it alum, or plastic [resin] either one will not draw lighting, lighting is attracted to a spike of energy coming up from the ground, or tree,
i wouldn't place it near the dish any way, put it on the peak as far away from the dish as possable, a copper rod 4 ft higher than the roof and dish will work, run a # 6 copper wire to an 8ft ground rod, driven into the ground,

Freakboynv is correct. Connect a number 6 copper wire (stranded or solid, insulated or bare) to the support bar of your dish. Drill a hole and attach a wire lug. Run that wire down to a ground rod pounded into the ground. Then connect that ground rod to your electric service ground, bonding them together electrically. Either in the electric panel or at the connection to the ground rod or water pipe as is the electric service. Do the same with your phone service ground rod. Bond it (connect it) to your electrical ground with the same size wire. You want all grounds bonded together for lightning strikes. You cannot divert a lightning strike with a lightning rod near by. The lightning will still cause a huge voltage in your dish. So ground the dish instead. You can do this yourself. This is a requirement of the National Electric Code. For good reason.

There is no way to guantee that your satellite dish will not be damaged if lightning strikes your house with or without a lightning protection system.
Most of the lightning s current will follow a properly designed and installed lightning protection system to ground.
But due to the enormous power discharge in a bolt of lightning some will likely still discharge through your satellite dish and cabling.
Good Luck.

Just get a 4ft copper rod and drive it into the earth, and then get either copper or aluminmum wire and connect one end to the copper rod and the other end to another copper rod mounted on the roof. Good luck.

maybe aluninum foil around it but if not go to a few stores and ansk them if they have lightning rods or get a copper pole and put it in the earth i wouldnt try my aluminum foil idea though thats just a guess

according to the NEC, all antanneas must be bonded to a ground rod with #6 solid copper wire minimum and must be bonded to the house grounding system. you will destroy expensive things unless you do your home work first on this one.
