Topband: WD-1A wire

[Dave Blaschke, w5un]

I've used WD-1A wire here for years for my Beverages, which are all over 
600' long. The receiver preamp handles loss OK in the forward  
direction. In the reverse direction I use a W7IUV external preamp due to 
extra signal loss. This is no problem on 160 or 80 meters.

Be careful with this wire, as if the insulation gets scraped somewhere 
along the antenna the iron core will rust through and the copper wires 
can then open. This has happened to me on several occasions.
