Ingo,
 
That is good news. I was planning on using 2m antennas anyway. Time to
experiment.
 
Many thanks
 
David

	hello david,
	
	as far as i know the range of the theremin can be improved
	when using bigger antennas. also there should be a trim poti
	on the pcb, if you have problems with the offset.
	
	good luck with your exhibition :-)
	
	best wishes
	
	ingo
