The so called safety choke to prevent the HV plate voltage from appearing on
the antenna in case of failure of a blocking capacitor. Normally a
commercial 2.5 MHY *RFC is used. Perhaps something wound on a ferrite rod.

The requirements for the safety choke are pretty tame compared to a
plate choke. The impedance level around it is 50 ohms (contrast it
with thousands of ohms around a plate choke), so you don't have to
maintain a particularly high RF impedance.

In other words, the same choke you used for the plate choke would work
just fine.
