Hi Joel,

I use a thin piece of lexan secured to a piece of thin copper sheet that I 
formed into a "shroud" around the patch.  Some people call it an "annular 
ring".

Absolutely no loss that I can detect, and the shroud seems to reduce stray 
interference at 2.4...  Mine has been up for over two years, and as good as 
the day I put it up there...Besides if a neighbor is "anti antenna"
and takes an "accurate" shot at your antenna the patch will survive!!

Keep the bugs "and bullets" at bay, too, Karl!!
