[sdiy] RCA theremin antenna shape

[pfperry at melbpc.org.au]

Does anyone know whether the horizontal (volume) antenna of the original RCA theremin is part of a coil, rather than just stuck on top of a coil?
Because, there is a debate on wheter the shape matters, or whether it was made like that so you could easily dip your hand in for a quick muting.
I suspect that it is a coil, and that the 'flattened' nature is to reduce the external field, so that it desn't interact so much with the vertical pitch antenna.
Any of you hams & RF guys? Harry??
