Now you can't coat your elements with it but if you have a solder
bath you can run copper wire thru it. The bismuth is brittle
but with the underlying copper it is stiff enough to stick it on the
antenna elements. I am assuming that the applied current would travel
along the bismuth coating instead of the aluminum and therefore should
increase gain for antennas that use coupling methods such as the Yagi
tho bandwidth may well suffer some what.
What do you think?

Since the conductivity of aluminum is about 43 times higher than that of
bisimuth, I think you are babbling.

Yeah, I too some of that from my neighbors yard, tried to make an antenna.

Cops came and took me away.

When I asked them why, they said it was none of my Bismuth.

You meant I could use the aluminum window frames as a big antenna?

Absolutely! But, don't you find the aluminum round tubing more suitable?

Absolutely!

For both AM & FM?

But, don't you find the aluminum round tubing more suitable?

But the window frame is right here!

YES! i have done that and it works great... even better than
bedsprings because you can make it vertically polarized by feeding in
the right place.

Did u solder a wire from the radio to the window frame? How did you do it?
