Ethernet to USB stop radar lightning strike?

Hi,

OpenCPN recommends that when connecting a radar ethernet plug to a PC you use a 100 mb or gigabyte switch to minimize damage from a lightning strike.

My HP PC only has USB C ports and I'm using a Plugable network adapter to a USB A hub, then a converter to USB C.

Does the ether to USB adapter act as a buffer to lightning strike?

Thanks,

Armand

None of that will help in the case of a lightening strike. The switch may act as a sacrificial component if you are lucky... But in general I would say that is bad advice.

Moo,

Thanks.

I definitely noted the recommendation of a switch in the radar thread, and maybe the concept was that it would be sacrificed rather than the laptop. We don't get a lot of lightning in the San Francisco Bay area, but I don't want to be foolish. On the other hand, adding a switch creates several more places for faulty connections. I think I have enough of those.

Thanks for your thoughts.

Armand
