not is to paint a like surface with the type of paint you are going to
use, place the antenna under it and test for signal acquisition.

Just in case anyone is actually interested enough in science to care, Mylar (polyester) is not reflective for RF. Metallized Mylar however is reflective to RF because it (surprise) is metallized.
