Chain link fence tensioning help please!!

[dinnertimedave]

Hi all, I'm putting up some 6' high chain link fence(the green plastic coated stuff) around the perimeter of my property prior to building a new workshop(plenty of questions to come there ) Problem I've got is that it is sagging quite badly at the top. The longest run is about 40', posts are 4 x 4 concreted in. I was thinking of using some 2mm stainless wire rope and turnbuckles to tension it. Would this do the job or do I need to go thicker??
Thanks in anticipation

I would go thicker such as this :

but you may also need these :

You could also go with the 3.5 mm wire from the same firm and just strip back the coating for it to fit into the gripple device.

Your only problem then is getting the correct tension so either get a few strong friends or one of these :
