Slightly off-topic, but...I was tempted yesterday to take pictures of the insides of the famous "Mini-State" antenna which RCA used to put out, and now is under a different name, I think. This is the "larger" garbage can style unit with the wired remote control and amp. A small motor rotates the elements in teh dome. In all honesty, I can see why, when I owned one (the one I had open yesterday had died) it was nowhere near as powerful as the old Radio Shack/Antennacraft RV antenna shown in the ad I posted earlier here! There is one driven DIRECTIONAL element laying flat on styrofoam in that dome, small "directors" glued-in, and a divided band of aluminum around the outer edge of the styrofoam drum. Really not much "meat" there to grab signals, and certainly not very "directional" even though it has a rotor! Apples to apples, the one I posted by antennacraft has more actual working "elements" and is likely tuned-better to begin with, and is THEN amplified.
