You can also use the airfoil shaped aluminum tubing that's in the brass/aluminum tubing rack at most decent LHSs.

It's dead simple and takes no time at all. Cut to length. Flatten the ends. Bend to fit. Drill holes in the flat sections. Glue and screw (or bolt) and you're not only done, but you've not added much weight and have added less drag. (An airfoiled "wire" can be about 10X larger than a round "wire" before it creates equal drag.)
