No, it is what it says, for static discharge. It won't prevent
strikes. Disconnect all cables before they enter your house and ground them. Ok thanks. Follow-up question then.......why do I want to get rid of the static? What if I don't? Thanks |

Unplugging the coax from the radio when not in use comes pretty darn close. No "device" can offer 100% protection against a direct lightning strike. Your both right, but you all forgot to tell him to unplug the radio from the wall too.

My tower got hit last year, no damage to my radios, they were disconnected and unplugged. I'm guessing due to an induced charge in the wiring in my house, I lost 2 TV sets, 1 computer, my router and wireless access point. I now unplug just about everything when storms are on the way. |
LOL,,only your off-topic sidestep definitions don't apply in this case.
The original poster was referring to a device, as in "gadget", not a "scheme",such as you presented in your desperate squirm for deflection. In fact, all had no problem comprehending such, with the sole exception of your self,,,...tsk tsk.,,and here you go again, the low self-esteem and self-hatred you are forced to deal with, ****ing you off to no end, manifesting in misdirected anger from your darkness. Such hostility for no reason other than your personal problems.....that makes you a .......lid. |

The antenna requires an earth ground, first, as required by
National Electrical Code. That mounting rod should be connected to an eight+ foot earth ground rod (available even in Home Depot and Lowes). This required by NEC for human safety, but also to protect transistors. Incoming wire should enter building at the service entrance so that a ground block (maybe $1 at Radio Shack or Home Depot) connects 'less than 10 feet' to the building's single point earth ground. Same earthing ground that also connects to AC electric, telephone, and cable TV wire. Do not even think an AC receptacle or water faucet will provide that necessary earthing. NEC requirements have changed since 1990 to require a service entrance ground rod. You may need to install this earth ground rod at the service entrance. Many homes don't even have that much which is another reason why some homes suffer household electronics damage. Principles are demonstrated in this figure. Note an antenna tower and building each have their own earth ground. Each is earthed as if it were a separate structure. Every incoming wire makes a connection to that earth ground. To make the 'system' work better, a ground wire interconnects the antenna and building earth grounds: http://services.erico.com/public/lib...es/tncr002.pdf Static is irrelevant. A few hundred volts of static will not damage any properly built radio. You could even static shock your car radio antenna or a portable radio antenna without damage. That would be as much as 18,000 volts - and still no damage. The earthing is required by NEC for human safety AND also provides transistor safety. If lightning is provided a path to earth ground via that exterior rod, then it too will not seek earth ground, destructively, via your radio. Direct strike lightning damage is that easily avoided. Unfortunately, too many don't have necessary earthing, suffer damage, and then declare nothing could have helped. Generations of technical history say otherwise. Its all about earthing - as even required by code. Zeeeeeeee3 wrote: Ok thanks. Follow-up question then.......why do I want to get rid of the static? What if I don't? Thanks |

Do you work for erico? http://services.erico.com/public/lib...es/tncr002.pdf Whats this link? Have one that works? Static is irrelevant. A few hundred volts of static will not damage any properly built radio. You could even static shock your car radio antenna or a portable radio antenna without damage. That would be as much as 18,000 volts - and still no damage. Sorry, static is not irrelevant. You need to read up on static damage before you make such foolish posts. Every electronics manufacturer in the world takes great lengths to control static. When you talk about static shocking your car radio antenna, or portable radio antenna without damage, you need to look at other paths that the static electricity would be taking. Would you allow me to connect your CB antenna connection of your radio directly to an A.C. line? Thats only 115 volts. The earthing is required by NEC for human safety AND also provides transistor safety. If lightning is provided a path to earth ground via that exterior rod, then it too will not seek earth ground, destructively, via your radio. Direct strike lightning damage is that easily avoided. Unfortunately, too many don't have necessary earthing, suffer damage, and then declare nothing could have helped. Generations of technical history say otherwise. Its all about earthing - as even required by code. Last time I read, current seeks all and any paths to ground. Has that changed? Direct strike lightning damage isn't as easy as earth grounding your antenna. Hopefully no one else will believe your B.S. that all you need to do is earth ground your antenna and electrical entrance box unless you are willing to pay for any damage that they receive following your instructions.
