[Milsurplus] What is this?

[James Duffer]

While in the attempt to clean out my garage I have come across this item.  It consists of what looks like aviation grade 1/8 in. stainless steel or galvanized stranded cable that passes through 16 heavy duty galvanized stakes that are 10 inches long and 1 1/2 in. diameter at the top.  The network of cable has three heavyduty copper alligator clips (5/8 in. wide 2 1/2 in. long) and a large spade type lug.  It is obviously military, as I bought it years ago at Ft. Belvoir, VA when they had a surplus outlet.  The card that I got states Engine Generator Ground Plane, but that is all it says.  On the item, are three yellow plastic labels on the cable.  Here are the markings"
80063 SC-C-681615
80063 SC-D-681611 Assy
80063 SC-C-681613 
The item weighs in at about 28 pounds and appears to never have been used.  I have never heard of engine-generator ground plane.  Most engine generator operation i have seen such as field day, only a ground rod was used.
 
Has anyone ever seen such?  thanks for any info that can be provided.
 
Jim
