when you are talking about lightning protection the first thing you need to look is your surrounding area. you may have a 40 feet structure yet you will not need that protection if the buildings or structures around the structures are higher and have lighting protection. my point is, you must think about this if you are thinking of making a cost effective system with good protection. still, for a better practice you can have this protection. for additional information you can have a look in this following site: http://www.rfimmunity.com/
