Likewise - 3 direct hits to the tower and nothing in the house damaged. Radios always plugged in.
Do it properly (don't trust me - google it). Lots of buried ground rods and copper strap and a single point of ground connection for the radio bench (only). Gas arrestors across all the aerial and rotator connections (and MOV's etc where appropriate). Radio bench isolated from house mains and all other electronic devices (optic fibre to PC). All the lightning arrestors (and MOV's) bolted to a single copper ground bus bar - the single point ground connection is from here to the tower ground system. This keeps the differential voltage across all the radio connections to a minimum. The caveat is - don't operate the radio (manually) in thunderstorms. Of course it's fine via the optic fibre. One lightening hit shook my teeth and made me jump a couple of feet into the air. Most things in the house with running software just crashed. All came good when the power was cycled - nothing was permanently damaged. To say I was relieved is quite an understatement. The 2m collinear at the top of the tower didn't survive. Shame the phone guys don't so it as well. If I get a tree hit by lightning in the front paddock the phone stops working (either immediately or the next time it rains). They replace the gas arrestors and dig up the cable. 73's Peter VK4JD -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of j...@kk9a.com Sent: Wednesday, 8 November 2017 8:12 AM To: elecraft@mailman.qth.net Subject: [Elecraft] Lightening damage Bingo! Of course the tower is not immune from lightning. Mine has taken many direct strikes and it has a number of ground rods. The ground system gives it a path that is not though your equipment. Also a single point ground and proper bonding as K9YC mentioned will keep everything at the same potential, minimizing damage.
