Phospher bronze was once easier to obtain than copper and was the ham
builder's material of choice for some applications that had to have a
degree of self-support. Apparently, it was easy to obtain in rectangular
form in the 1920s. I recall one of my father's emergency rigs being an
oscillator with a large multi-turn planar coil of phosphor bronze used as
both the output tank coil and the antenna. About 1/6th the conductivity
of copper (9.1E6 vs 5.8E7) but about 7 times better than stainless steel,
which is commonly used in whips. So its use in linear antenna wires does
not appear to be countra-indicated.
