Our flag gear is as follows:
* 21′ of pole (rigid pvc) cut into ~3′ sections plus a hoist bar
* hardware/eye hooks
* paracord for guy wires
* 7 nylon straps with metal cinches/clamps for clamping it to the tower
* 10′ flag (14′ corner to corner)
Since the wind is blowing from the North/Northwest, our plan is to lash it to the most southeasterly side of the tower so we have optimal wind pickup with guy wires anchoring the flag down along the rails of the tower.
