No, that is not a convention. They should follow the black is ground and red is hot but sometimes quality control isn't what it should be.

The black/ground/shield side usually has a small tab or something to identify it as being connected to the coax shield. *Marshall Harrison, * *W4MKH* On Mon, Aug 29, 2022 at 10:32 PM Bill Lederer <[email protected]> wrote: > Team: > > I have been using a wire out the window from my upstairs office for an > antenna for my kx3.
