Roof mounted digital TV antenna

The precise course lightning takes is going to usually be the one of the very least weight, therefore if I follow your logic, you are convinced that by grounding it, you're decreasing the weight and therefore enhancing the likely-hood of a lightning attack.

I do believe the stark reality is, if lightning could hit your house, it will hit home. By grounding your antenna, you are not going to divert a strike that could have usually gone to your neighbour's household, basically, the fact that they will have a grounded antenna and you do not doesn't mean they truly are safeguarding you against a strike. Now, if it was a 300' antenna, that might be an unusual story, but on scales we are speaking about, i recently do not see it.

So what now grounding it's going to do is make it much more likely in the event the home does get strike, it will probably strike the antenna and follow the surface line down seriously to ground. Lightning continues to be wanting a path to ground. If it happens to be by hitting your television antenna, following it into roof, going across some blinking on your roofing to an attic-mounted fan, after which throughout your electric wiring, which is how it's going to get. It may be along the part of a rain gutter, throughout the phone wiring and along the utility pole. Aim is, you're much better having it feel the path you produced rather than own it discover unique means.

Bear in mind, though for typical wiring/electrical purposes we would start thinking about products like asphalt shingles, lumber, and synthetic become insulators, when you are talking about the 10 to a huge selection of megavolts that lighting effects has actually, all those materials tend to be conductive (steel is a better conductor).

I believe you are safer to have it grounded. Just be sure to put in good rise security on cables to arrive (make sure the coaxial range from antenna experiences a surge protector).

Honestly, it's a good idea to possess rise protection on any sensitive electronics anyways. Regardless of if lighting strikes your neighbour's home or a computer program pole, there is a good chance you are going to at least have actually current surges on your power/phone/etc lines that may damage anything plugged into them.
