Topband: Fw: WD-1 Wire impedance

[Herbert Schoenbohm]

But believe the WD1A really works well at this QTH in both forward and 
reverse modes.  I have made many direct comparisons on extreme DX on 160 
and the WD1A was the difference it too to hear the weak signal.  My 
tests on the VK0 and VP8 Dx-peditions with a 600 foot single wire 
Beverage and the WD1A reversible configuration of the same length made 
me a firm believe in the WD1A Beverage ability.  Furthermore the WD1A is 
cheap, strong, easy to construct just passing over limbs of small 
trees.  In fact it is so strong that when a deer (yes we have them here) 
gets caught up in them the far end boxes, until I put in break away 
jumpers, was the victim.
