[i] now don't kill me for saying this, but i don't really see the difference between having a theremin with one antenna and a volume control knob/dial and one with two antennas, as long as the theremin creates a pure sine wave tone, do you really need a volume antenna?[/i]
To be able to play separate notes, you have to have a volume control antenna. You can't reach over to the unit with your other hand to twiddle a knob to separate the notes: the presence of the other hand would alter the note you're trying to play.
It's my opinion that it's better to save your money until you can afford a real and decent theremin, instead of getting some horrible cheapo noisemaker and just calling it a theremin.
