For the Kenwood R-1000, I want to find a wire just like the one used in
the ANT-60 wind-up antenna, because the wire is flexible, black, housed
and small.

Does anyone know where I could find about 100 feet of this wire? (Not
the ANT-60 wind-up antenna).

Have you checked a hardware store like Home Depot or Lowes? I've gotten wire
in all sorts of gauges from Home Depot, in the electrical department.

Here is a good link to many different types of SW antenna:
