Antennas usually are made of aluminum as copper is somewhat heavier

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?

testing, 1, 2, 3... can you hear me now??

i guess the logjam finally broke. google has been bouncing and
queuing these up for days now!
