I just hung about 200 feet of wire in a straight line .

Would there be any benifit to doubling back?

I ran out of property space..

That depends. If you double it back next to the length of wire already
run then it will not do much of anything. However, you could make a loop
out of it. As an example if you already have a 200 foot run to the back
of the yard you could then continue it across the back of the yard and
then back to the house.

You would have created a triangular loop with three sides of more than
400 feet. That is a good size loop. The ends of the loop would be
connected to the inner and outer coax conductors. Which end loop is
connect to the inner conductor probably does not matter except for the
local noise it will pick up.
