SMA Adapters:

That should provide most any connector you might want to throw at the thing.

I might as well take the time to add that if you want to cable
directly between USRPs you should use an attenuator, and it might be
worth while to get some kind of combining circuit if you wanted to do
spectrum analysis as well.

Most of the attenuators and combiners I've used come from here:

I have to admit I don't know their pricing, but they are very high
quality from my experience.
