I wanted to ask about this before I started making parts...
If I use an anodized aluminum antenna mounted in an anodized aluminum clamp (with a proper conductive connection to the antenna independent of the clamp) is there enough conductivity between the antenna and the clamp to create undesirable noise or interference? The clamp would be mounted to a plate that the circuitry will also be grounded to.
I can isolate the clamp from the plate, but it requires a bit more machining (including a new reamer) to isolate the bolts from the plate using phenolic spacers. I'm hoping not to isolate the antenna from the clamp, as any interface material makes the antenna a bit "floppy."
I can machine the clamps out of a plastic, such as Nylon 6 or Delrin, but I'd prefer to use 6063.
Standard analog type theremin.
Thanks!
