Do optical mirrors still work in the microwave regime? I have no idea. -TD

Telescopes are sold for < $200 which include programmable positioning devices (2 axes obvioiusly). I suppose its just a reduction drive and the usual electro-mech-control stuff but it implies a high degree of angular resolution for cheap. Has anyone:
1. ever used the refractor type telescope tube as-is as a super-long pringles directional 802.11 antenna? In fact the front optics may not interfere...
2. ever used the electronically controlled mount on a steady platform and a highly directional antenna (dishes included) to really see what the world really looks like at 2.mumble Ghz passive with an 802.11 decoder? I mean, radio astronomers do detailed sky surveys all the time. Why restrict yourself to the sky?
(Yes, I realize our friends at Ft Meade have probably been using scanning-tunnelling-microscope type piezo-servo actuators to keep a steady gaze for some time..)
