I think I have the same model.

One other possibility, just in case you have that kind of gear: if you have any classic (thick Ethernet) transceivers, you can connect a thick Ethernet cable to a thin one.  Just use an N to BNC adapter (barrel, not T connector as some fools at the magazine RSTS Professional did years ago).  You'd apply the thinwire cable length and station count limits, in the unlikely event it matters.  Terminate at each end (of the whole cable assembly) as always.  Both cables are 50 ohms, which is sufficient (the differences in cable loss and propagation velocity are irrelevant).
