[R-390] 390 ant balanced connector

[djmerz at 3-cities.com]

Hi,  I'm looking for the 82-5589-rfx connector and a short piece of
approprite coax twinax cable to use with my 390.  Mouser, Newark, Surplus
Sales and Wallco have the connector with Wallco lowest at $4.  But I still
need to come up with the cable.  Someone sold me a made up item for under
$10 a few years back when I was getting the 390a up and running - I
thought maybe someone here might know or be a source for such a combo, so
I don't have to buy some large quantity of coax,  thanks for help,  Dan.
