Best place to buy BNC to RJ45 adapters?

A hub would also enable you to build a tiny coax segment for your 10Base2 cards and then use a single hub to adapt that to a twisted pair (RJ45) port. This may or may not work with a coax to twisted pair converter/transceiver.

Watch out: a coax segment is built in a completely different way than a twisted pair network. You will need a T-connector for each network card and the hub. These T-connectors are daisy-chained with RG-58 cable and the first and the last T-connectors are equipped with terminators.

Thanks, everyone, for your input.  Do you think I can use the following adapter if I find a BNC cable with two male ends???

No. That item should not be called "media converter" because it isn't. It's a simple electrical adapter that just won't work. A real media converter will require a power supply for instance.

The smallest coax (10Base2) setup you'll require (i.e. to connect the NIC and the converter/hub) is:
- 2 terminators
- 2 T-connectors
- length of RG-58 with BNC connectors

Any further device will additionally require:
- T-connector
- length of RG-58 with BNC connectors

If you've got several coax devices you can set up a small 10Base2 network and adapt that with a single hub / media converter.

Alternatively, if you've only got a single NIC equipped with an AUI port it's much simpler to use an 'AUI transceiver for TP/10BaseT' - paid ~4 € for mine on eBay. I think any model will work.
