How Much Does It Cost To Install Thunder Protection/ Lightning Rod

I wish to known how much it will cost me to place thunder protection in my house the home is one storey building.The electrician explained it will definitely cost me 387,000 naira due to the dollar rate is too much now. I wish to know if it’s true which materials will I buy. The Electrican also explained he need to purchase wires he will use to connect for all the 14 rooms to fix the thunder protection.
