Thanks, gentlemen.
Obviously, being a conductive path from a higher point to ground, it conducts the lightning strike safely avoiding the building to suffer the effects of an immense current. But that is when the lightning strikes.
My interest is for all other non-striking times, the conducting rod presents a path to discharge to ground the buildup of any coronal charges of any polarity ionization in the air;
by repelling or attracting or nulling or both or other effects to buildup of charges in the air vicinity ?
The alleged 45 degrees 'cone of protection', who/how was that calculated ?
Is there something that you find wrong in the following explanation, were the protection effect/function is more by repulsion than other ?
Am I interpreting it wrong; or should not apply to real life lightning phenomena ?

Other words... Installing a lightning rod , in your opinion :
- increases the chance of lightning to strike the rod safely conducting the danger away from a building, or
- decreases the chance of lightning to strike the rod by repelling buildup of charges ?

Does not seem effective all the time :
