I see the humour genes is alive and well in some hams!
But seriously plastic coated wire will work on HF antennas, though
you may see a slight lenthening of resonant length vs bare wire.
My 80m/40m fan inverted-V is made of coated copper-weld and I just
tuned it using my MFJ-269B antenna analyzer. My 43 by 122-foot
inverted-L (630m band) is also the same copper-weld steel. It uses a
huge base coil that set the tap for resonance. Z = 20 +0j It warms
worms well in the winter with 100w input and 4w EIRP.
Years ago I made a light-weight 80m dipole using 18ga speaker
wire. Worked Anchorage over 500 mi with 100w from a checkpoint on
the Iditarod Sled Dog race.
