If hooked up the other way it would effectively be 186-ohm shielded balanced cable.
And if you hooked it up both ways, it would be a 4:1 BalUn. -kinda-

And, if you solder _everything_ together, they make great radials.

Long story (sort of) short: Back in the early 90's when the U.S.
building and/or fire codes outlawed the material then used as the
outer jackets on RG-62 and the such, a large bank where I was
consulting had to rip out a gazillion furlongs of it from up in
the ceilings of the building. (Probably A Real Good Thing -- if
for no other reason than they always put in "new stuff" for each
new generation of terminal/monitor/display that came along. The
ceilings were overdue for a complete colapse...)

I hauled off as much as I could load into my trunk each day.

By fabricating 1/4 wave lengths of the stuff paralleled in sets of
2, 3, and 4, I built matching sections for various Field Day verticals.
I used the "worst" of it for radials on a 2-element, phased 40M
vertical -- and used 2-pair paralled runs for the phasing section(s)
between the 2 elements.

Used a grid dip meter and receiver to cut the stuff to length.
