[BC] Where can I find.....

[Mark Humphrey]

I just checked; the outer diameter of the threaded portion of an OIB
connector is about 1/4 in. smaller than the female LC and doesn't have
a recessed inner contact.

Even if they did mate, most of the male LC connectors I've seen are
designed to attach to RG-17A/U and use the solid center conductor of
the coax as the center pin, so it would be a bit tricky to adapt them
to make clip-on leads in the same way as Delta's.

A couple of years ago, I priced the BNC to OIB adapter that Delta
offers and I recall it was around $150, more than I paid for my
bridge!  I searched for an alternative source and had no luck.

So instead, when I need to connect my generator to the bridge, I use a
BNC to banana plug adapter -- not the black plastic type Pomona makes,
but the older metal version with offset ground pin.  I removed that
ground pin and substituted a 2 in. long braided jumper which is
fastened at one of the screws around the OIB connector.  It fits very
well but can be pulled out of the way when I need to attached the
alligator-clip cables.
