If you are talking about lightning damage the screen room will not help if 
you have a direct hit or very near one.
With a direct hit on antenna or screen  room most likely the screen wire 
will simply vaporize. If you have a very near hit
the current thru the screen wire will produce enough voltage drop for EMF 
to enter into the cage.
