Does a lightning antenna protect you house !00% from lightning strikes?

Question

Does a lightning antenna protect you house !00% from lightning strikes?

Answer 1

Lightning rods do not protect 100% from Lightning. Lightning rods just provide a path of least resisitance for the electrical charge to travel.

Do TV antennas protect structures from lightning?

No! Your television antenna is a target that does not have adequate ground to safely conduct a lightning bolt to ground.

I have a lightning rod on my house. Am I safe from lightning?

Lightning rods will not prevent your building from being struck. They actually INCREASE it by making your house TALLER. The purpose of the lightning rod is to direct the current from the lightning to the ground along a preferred path instead of to the house. However, this works only if the rod is connected to the ground with heavy gauge wire.

Do conventional Franklin rods adequately protect buildings containing microprocessor based systems?

Answer - Lightning rods have been perceived to provide protection from the damage caused by lightning for over 200 years. However, it is important to remember that the purpose of a lightning rod system is to prevent physical damage and to keep the protected structure from burning down. That is why lightning rod systems are covered by National Fire Protection Association standards. All we were concerned about was keeping the barn from burning down. Lightning would strike the lightning rod and be conveyed by the conductor system ground, and the barn would not catch fire.

However, now we have structures with lightning rod systems which contain microprocessor-based equipment. Lightning still strikes the lightning rod and is conveyed to ground, and the structure still does not burn down.

However, now none of the computers work after the strike. That is because, although lightning rod systems are relatively effective at conducting the discharge current and the associated heat away from and around the protected structure to ground, there are other types of damage from a lightning strike; secondary effect damage, damage caused by currents induced by the electromagnetic field effect, and damage caused by changes in ground potential across a site.

While the lightning rod prevents most physical damage, it cannot mitigate these types of damage.

Answer 2

Absolutely not, especially if the antenna (I guess you are talking about a TV antenna) has those traditional "lightning arresters."

Such lightning arresters only protect against minor strikes.

You need a lightning rod to fully protect your house against lightning strikes. A lightning rod channels lightning to the ground by a technique similar to the proper techniques of electrical grounding....without harming the house.

Remember what Benjamin Franklin did....and this will help you just a lot!
