No, antiparallel means one diode in each direction.

What you want is to reverse one of the diodes in your schematic.

This gives a composite device with high impedance at low voltages but with the ability to carry fault current with no more than a volt or two across it, in either direction.

I use two chokes, one on each side of the antiparallel diode pair, but one should work fine. The idea is to block low-level noise without compromising safety.

Try this without making major physical changes first. The tweak works on my equipment, but I have not heard from many others about it.
