We all know we could debate this subject to our fingers bleed from typing The fact is if your equipment is not grounded correctly and you do get hit by lightning that your insurance company may deny your claim. Whether your better off not grounding your equipment is not what the NEC states. I have had antennas mounted on a roof that where not grounded at all and have been hit by lighting. The coax was disconnected hanging down the side of the house not touching the ground and the end was within a foot from a iron fence. The lightning followed the coax jumped to the fence and went to my neighbors house and blew and I mean blew his electrical panel right off the wall. Just because the installer didnt ground those dishes doesnt mean they are immune to a direct hit. Just a luck of the draw. Of course even with a properly grounded system a direct hit by lightning isn't going to save your dish and more then likely may damage your equipment (the power of nature). The final and most important thing here to remember is, the main reason for grounding your dish and coax is for protecting your equipment from static discharge not a direct hit from lightning.

Grounding anything in your home does not guarantee safety from lighting strikes. The purpose of grounding the dish and coax is for static discharge. During storms if there is a lot of lighting in the area it can sometimes be close enough to create static in electronic equipment. Planes even create this energy under normal flying conditions. This is why airplanes use static dis chargers on the aircraft for there on board electronics. This is why it's very important to ground your dish and coax. It gives the static buildup a path to discharge. To give you an example we are all familiar with is what happens when you drag your feet on the carpet and touch something, zap!! You just discharged all that static buildup. Last year one of my co-workers grab a different chair to sit on and within one week he had replaced his phone headset four times. We finally narrowed it down to his chair in which every time he sat in it he built up enough staic that when he picked up the phone he would get shocked and it blew the headset. This is the purpose of the grounding your satellite equipment. Dish and coax.
