A lot are using it Roger,  The I squared R losses are low because signal currents levels are so low..   Especially for BOG antennas, the physical  strength often outweighs the loss.   I am using it for a 300 foot 2 wire switchable Beverage &  works well.   For real long Beverages, maybe a better wire should be considered.

I know that WD-1 and WD-1A wires are not very good for two wire transmission lines due to their high attenuation. I wonder however whether they are OK with the conductors strapped as Beverage wires? WD-1A has quite a few advantages for the bush where I run my antennas - it is strong, it is quite light, it is very nice and easy to run out, and it fits through electric fence insulators. I presume that its poor performance as a balanced line is related to the copper wires twisting with the steel ones meaning that for some of the time current is passing through the steel wires due to skin effect. On the other hand I can't see how it can be worse than galvanised steel wire or electric fence wire.
