This thread has been around for almost 10 years, and so has accumulated an amazing breadth of information on proper grounding of OTA, Satellite, Cable TV, and Telecom gear. I was going through this thread again from the beginning in order to write a summary of best advice, but frankly the sheer quantity of great advice makes it too big a task. Instead, the following tip shows how to make use of the existing info here for your quick and easy reading:
Use the Search This Thread tool to the upper right beside Thread Tools and put in a search term such as "attic", or "insurance", or "lightning", or "electrical code", etc. to find highlighted posts. From there you can click on each post to follow the discussion about it at that point in the thread.Go ahead and give it a try! As with all encyclopedic threads like this one, don't make decisions based on one or two posts or opinions! Proper grounding is far too important a topic to be treated so lightly.
