> If US bases are leaking signals that can be intercepted by drones overhead then these same signals could be just as easily intercepted by cars driving past the bases or nearby homes
Not really. Some signals can be very much unidirectional (eg, visible only to an overhead drone) instead of omnidirectional (eg, a car).
Just curious; what kind of signals would be uni-directionally beaming upwards? For communicating with aircrafts that directly hover above the base? Wouldn't that be really limiting in terms of usefulness?
