I hope this section is OK for posting as I didn't really see one that fit. I want to install one of the twin wire lead horizontal CB antennas (17' long total) in the attic of my home. I belong to a SNOOTY home owners association (yeah, dumb, I know) that frowns on antennas so for something big enough for CB I have to go to the attic, unless I put some small vertical antenna on my porch which seems like a pretty ineffective solution.
Now, here is the problem...
Being of newer "energy efficient" design the home uses a "radiant barrier" on the bottom side of the roof sheeting. I cannot testify as to what the thickness of the material or to exactly what it is, but I would think it is metallic. Only on two small sides is the roof a "gable end" which this wouldn't have the stuff. In MOST directions, the signal woud have to travel through this stuff (assuming it would - I don't know thus the question). How much trouble is this stuff likely to cause in this frequency range? I am guessing that at certain frequency ranges it would cause huge problems, where in other areas of the spectrum it wouldn't, I just don't know which is which. Would it still likely be better than a 48" "porch antenna" on my porch?
