There was some open wire around when I was a BT (Post Office) 
apprentice. It was solid copper wire. As I recall, dropwire (steel 
with a thin copper coating) had a limit to its usable length because 
it had a higher DC resistance than open wire. This resistance may not 
be high in relation to other losses on an LF Marconi, but it would 
rule out its use in a transmitting loop antenna.
