The airport is about 50 miles or so from those mountains - they are a  
lot further than they look.  The glass is also reflective glass,  
which has a metallic film in them.

As for a low power digi by the airport, the airport is *huge* as far  
as land coverage (largest in the US - by far; heck, one runway is  
around 3 miles long, and that is a small fraction of the airport land  
area - the airport owns tons of land to minimize noise complaints),  
there are tower restrictions outside the airport, etc.  I would be  
surprised if you could get a digi closer to the terminal than 5  
miles, and probably not with a lot of tower height.  I'm not sure  
that would be enough for a D7 inside a faraday cage.  I know that  
even receiving the ATIS broadcasts off the airport property can be a  
bit iffy with a mobile rig on the ground.
