I am working on a small PC board for the RPM
counter. Some people think I am crazy for using
these cheap TV set video connectors and video
coax for wiring CAS's and injectors.
The justification is it is automatically shielded.
An RX8 CAS, injector switching and flywheel tooth
sensors can put out some  extraordinary frequencies.
You don't want to hear them in your radio.

Here is the PC board coax connector I will
be using. This are mass produced in the billions
so they are very cheap as coax connectors go.
One can get fire resistant braided Teflon insulation
coax.

I think you're crazy..  For completely unrelated reasons..

Just kidding.  :)

RG-58 Coax is kinda bulky.  There are other, smaller diameter 50ohm
cables.  And since neither the source nor load are 50ohm, it doesn't
really matter what the cable impedance is.  You could even use plain
vanilla shielded wire.

True but most mating female connectors are 50 ohm coax.
Also the cable is cheap as there must be a zillion
miles of the stuff out there.
