Peter, You will find some attenuation of signal and the noise figure of your LNA will be close to 290 degrees K. How about a glass skylight if your antenna needs to be indoors?

I am finally getting around to mounting some antenna's in the attic and was wondering if I should set up my ADIC 3731 with corner antenna? The roof does not have any insulation and as far as I can see only asphalt type roofing shingles over wood. Any thoughts would be greatly appreciated! Hope everyone had a wonderful Thanksgiving! 73 Peter KD0AA
