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. Since lightning often strikes tall objects first the lightning rod on the first floor would not allow the current to be safely sent to the ground.
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).
A lightning rod is designed to attract and divert a lightning bolt and has no power of its own
The ground
A lightning rod is a metal rod placed in various structures to prevent lightning from striking them. It attracts the lightning to itself, and it is channeled into the ground.
About 2 feet tall
A lightning rod mounted on the first floor of a tall building will not work because lighting strikes from above
No. Since lightning often strikes tall objects first the lightning rod on the first floor would not allow the current to be safely sent to the ground.
The kite and rod was his demonstration. In modern terms it is a lightning conductor or a lightning arrester. This is usually a metal (copper, or iron) rod placed at the very top of tall buildings, church steeples, tall industrial chimneys.

hold a lightning rod up to the sky while lightning is striking
I do not think you would need to insure an lightning rod.
The ground
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.
