Antenna in attic with radiant barrier
 

I'm in a very similar situation with regard to the radiant barrier. I have an antenna that worked great in the attic of my previous house, but just moved into a new one with radiant barrier. I only moved about 2 miles and went from a one story to a two story. My question is, how big of an aperture do I need to make in the radiant barrier for my antenna to work if it's placed within 2 feet of the edge of the attic? I'm more than willing to clear out a 6x6 foot area of radiant barrier if it would return my beloved OTA

I'm only concerned with receiving the channels in yellow (same ones I received at my prior address)
