Yes-- and every piece you mention is "quality radio design 101".

I'm not sure about that.
The biggest most suspicious thing is, if they're resourced to investigate everyone with a piece of coax going outside-- where does yours plug into?
Of course, if you're really dedicated-- get a satellite TV receiver, empty out the nice metal box, put the receiver inside ;).
Such a device would likely look peculiar enough to be easily recognizable, though, so you'll need to hide it, possibly inside some innocuous-looking other device or enclosure.
The whole setup becomes somehow more involved, but still cheap enough.
