Commercial BNC DC-blocks don't seem too common - I can't recall seeing one, only inline through terminations and attenuators etc.
With N-types etc. DC-blocks being much more common, as were supplied with some Spectrum Analysers etc.

You could get small BNC Plug-to-socket boxes from RS, to add your own parts inside. But they are a bit bulky (and not that cheap).
Although could make something similar from a couple of back-to-back BNC sockets, with spacers in-between + a plug-to-plug adaptor.

Or if you can get one of those (RS etc) inline BNC attenuators, cheap, then most unscrew apart and just have some leaded resistors inside - which could be replaced with a capacitor.
Good info

I'll have a look for some inline DC blockers

Do you know if these are any good as attenuators?
