Hi JB,

I remember comments on a similar situation from an old QST.

In June 1977, Barry Boothe W9UCW recounts his success.
His "Beverage" was half a mile long, on insulators, three barbed 
wires above and three below, steel poles, and the wire was 18/24 
inches above ground. He terminated it by connecting it to the barbed 
wires at the far end. In fact, it was an out-of-season use for his 
electric fence - the horses were in the barn for the winter. Barry 
commented that it worked extra well and was the most directional 
Beverage he had ever used [on 160m.].
Your proposed wire along the top looks better than Barry's which was 
half-way down the fence. In passing, his "hot" wire was No.16 galvanised steel.
Good luck.
