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.
