I have a flag pole (scaffold pole really) which is about 4.5m high and buried in the ground in concrete. Attached to the pole was a shade sail. Unfortunately when the wind blows with the shade sale attached the pole moves too much, so I've had to take the shade sail down. I've decided to put up two steel guy ropes to support the pole, but wondered if there is an optimal distance from the pole for maximum support. Can anyone advise?
