Need Help with Building Antennas for Etherwave Pro

Hi everyone!

I’m currently working on figuring out how to rebuild the antennas for my Etherwave Pro, which were unfortunately stolen. I’m looking for technical drawings or any documentation to help me create the pitch and volume control antennas. Any advice on design, materials, or the process of building them would be greatly appreciated.

If anyone has experience with building or replacing these antennas, please share your drawings, tips, or ideas! I’d also be thankful for any recommendations on tools or methods for the job.

Thanks in advance for your help!

Hi Mykyta,

A while back someone who owns an EPro sent me the following information regarding the pitch arm guts, hope this helps:

Inside is a string of coils in series:

Input
11mH (with trimcap in parallel with it)
4.7mH
11mH
11mH
Antenna

Total of ~38mH

Current value of the trimcap is on the order of 4.7pF

Henk Brand knew the EPro inside out, but unfortunately he died recently. Thierry knows it well too.
