Feet Copper
will lightning still travel through a disconnected coax cable?
i have a 12 foot outdoor tv antenna attached to a 30 foot mast on the end of my house. i have it properly grounded to the specs recommended so that both the coax traveling down the mast is grounded to an 8 foot copper ground rod, as well as another #10 copper wire runs from the mast itself to the 8 foot copper ground rod also. whenever i know that a storm is approaching ,as an added precaution i still disconnect coax cables and unplugged my tv’s, computer, etc… my question is.even though i disconnect my coax cables, will lightning still shoot through the disconnected ends? i was reading an article on another website and if i’m understanding correctly they say disconnected coax cables lying around on the floor in an electrical storm is like having a stick of dynamite lying on your floor. is this true?
It’s not that bad.
Lightning will do pretty much whatever it wants, however grounding things will help. Disconnecting the coax will protect your TV from anything that gets through, however having is disconnected it not “like a stick of dynamite”.
