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.

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.
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.
The lightning rod (USA), lightning conductor (UK) is a metal rod that is placed on the top of tall buildings. A metal cable or strap connects the conductor to another metal rod sunk deep into the earth. The principle is that should lightning strike the building, it is attracted to the conductor and travels down the cable to be dissipated safely into the earth - so saving the building from lightning damage. Wooden building used to burn down under stikes from lightening. The lighten rod (Ben Franklin) gives the electricity a easy path to the ground instead of a heat-producing path through wood.
