A client contacted me today regarding an issue he started having with his Directv at his workshop. I have never been to this location, only his home. He indicated they recently upgraded all of the 8' florescent lamps (and ballasts) with 8' LED lamps (and ballasts). After this occurred, the flat panel Directv picture goes to snow (his description) until the new LED lamps are turned off. Then the picture is clear.
Coax and HDMI cables are approximately 15' away from the nearrest LED lamps.
He explained the dish is mounted near the ground on a pole. I haven't installed a dish for over 20 years, so I don't know if the dish's mounting pole is a suitable ground. He doesn't think a grounding block exists where the satellite feed enters the building. Could it be that simple, or is there more to this? I did a Google search on the topic and found next to nothing relevant. I will probably go out there sometime next week. I wanted to be as prepared as possible. It is at least 45 minutes one way.
