If you need a covert way to get transmissions to and from PB, you could always use the AT&T Long Line Microwave Repeater system that was built across the country in the 50's and 60's. It was shut down in 1984, but most of the sites where sold off, which doesn't mean that MPI couldn't have bought most of them up and continued to use them well into the 2000's
Since the list of industrialists is long and full of very important companies, it would stand to reason that AT&T would be on this list somewhere.
There is a series of towers that runs thru northern Nevada south of PB. It would be easy to camouflage a single thru this system.
A good history and further site links :

You can also poke around on this site to get the locations of the current system :
