[Lowfer] A little lower than lowfer...

Maybe someone can advise...

I have a 14 channel ultrsonic transmitter I hve been playing with.  It is
fairly low power, at least to me, my wife smacked me when I turned it on in
the house, and broadbeamed.  I haven't measured the frequencies yet, but I
would guess the highest is around 18 KHz.  I am in need of projecting this
acoustic wave about 700' at about 100' max divergence.  I have a 2' aluminum
parabola, would this work for this purpose?

Is there a list around that deals with this sort of experimentation?
