it doesn't have a fixed length, as long as a rod is "grounded" connected to the ground by a heavy duty wire, it's a lightning rod. . .
No, a lightning rod should be mounted at the highest point of a building to effectively capture and divert lightning strikes away from the structure. Placing it on the first floor would not provide adequate protection for the entire building.
Lightning follows the easiest path to discharge its energy. Ionized air during a storm causes the lightning to seek that quickest path. A lightning rod's sole purpose is to attract any lightning in the presence of ionized air to come toward the rod. So for example, lightning will seek the closest metal or tall object (including humans).
When lightning strikes a lightning rod, the rod provides a path of least resistance for the electricity to travel safely to the ground. The lightning is then conducted harmlessly into the earth, minimizing the risk of damage to nearby structures.
A lightning rod is a metal rod or conductor mounted on a building or structure to protect it from lightning strikes. The rod helps to safely conduct the electrical charge from a lightning strike to the ground, reducing the risk of fire or other damage to the building.
A lightning rod is a metal rod mounted on a structure to divert lightning strike away from the building and into the ground, preventing damage from electrical surges. When lightning strikes, the rod provides a path of least resistance for the electrical current to follow, minimizing the risk of fire or other damage.
About 2 feet tall
Yes, a lightning rod mounted on a tall building can help protect the structure by providing a path for the lightning strike to safely reach the ground without causing damage. The rod will attract the lightning strike and conduct it harmlessly to the ground, reducing the risk of fire or structural damage. It is important for the lightning rod to be professionally installed and maintained to ensure its effectiveness.
Benjamin Franklin's invention of the lightning rod helped protect structures from being damaged by lightning strikes. The rod functioned by attracting lightning strikes and safely redirecting the electrical charge to the ground, thus preventing fires and other damage.
856m tall without the lightning rod
No, a lightning rod should be mounted at the highest point of a building to effectively capture and divert lightning strikes away from the structure. Placing it on the first floor would not provide adequate protection for the entire building.
The CN Tower has a lightning rod to protect it from lightning strikes, which are common due to its height and location. The rod safely channels electrical energy from a lightning strike into the ground, preventing damage to the tower and ensuring the safety of its visitors and systems. This protective feature is essential for maintaining the structural integrity of such a tall and iconic structure.

A lightning rod (or lightning protector) is a metal strip or rod, usually of copper or similar conductive material, used as part of lightning safety to protect tall or isolated structures (such as the roof of a building or the mast of a vessel) from lightning damage. Its formal name is lightning finial or air terminal. Sometimes, the system is informally referred to as a lightning conductor, lightning arrester, or lightning discharger; however, these terms actually refer to lightning protection systems in general or specific components within them. The term 'lightning rod' is also used as a metaphorical term to describe those who attract controversy.
I do not think you would need to insure an lightning rod.
The lightning rod enabled people to have a system that prevented their house from being struck by lightning. It is a metal rod that prevented lightning from striking. Instead of striking the target it bounced off the rod and into the ground.
