A blocking cap like 1000pF should do it. As for what to use to feed the power supply to the preamp, likely it would be a choke coil that passes DC but blocks RF. Something around 1 microHenry. Not at all critical. The 75 ohm impedances in this system should swamp out any resonances from the cap and inductor anyway.
