[sdiy] RCA theremin antenna shape

[Tom May]

According to the R.C.A. Victor Co., Inc., Theremin schematic, both
antennas are just antennas stuck on top of coils.  Although the pitch
antenna appears to be connected to the variable pitch oscillator's
coil via two more coils and possibly an unlabeled capacitor in series.
