I seem to recall Radio Shack selling this type of "antenna wire", which is perhaps more properly called "phosphor bronze".  I have never found a record of any such wire used with aircraft equipment (my peculiar interest) back in the HF days.  The roll of Radio Shack stuff started sagging almost immediately every time I tried to use it, which is why I quickly shifted to the Copperweld type that the Services used.  The link below mentions that the "...electrical conductivity of phosphor bronze is about 15% that of pure copper."  That may or may not be of any interest to you.

Can someone tell me what the antenna wire is called that is milsurplus and as often obtained on fly fishing rods.  It was military antenna wire and was about #22awg I think (might have been as big as #18 but no bigger).  It is/was a bronzed copper woven copper stranded wire.  I posted the same question on another list but was told to use copperweld (I hate that stuff) or to buy some stainless steel wire (even worse).  The wire I am looking for is for temporary portable operation as a dipole or two or three.  Yes I could just buy a couple rolls of insulated wire to make this antenna but had some of the bronzed wire in the past and it would be ideal for the operation I have planned.

Thank you.
