I have four beverages here and they all use WD-1A. They work very well. My
only issue is that, during the summer, the calves love to chew the wire.
The older heifers and cows ignore it, by and large.

Subject: Topband: WD-1A wire
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.
