[Elecraft] Big antenna - Collins 13 ele Log?

[Darwin, Keith]

What is the biggest antenna you've ever used?
 
In the mid 80's I had access to a 13 element log periodic that covered
40 -10 meters.  It was 200 feet above ground.  The club station had a
Henry amp to drive it.  Man, what a signal!
 
Anyone know anything about this antenna?  I know it was made by Collins
and was apparently designed for military use.  At 10,000 lbs, it sure
was big!
