[QUOTE="Old Fred, post: 22088"] I think the best advice is "don't risk it". A 70cm dish has an area of roughly 3,850 square centimetres. A 1.25m dish is about 12,300 sq cm. So divide them and you find that the larger dish is a LOT larger - it has more than 3 times the area. That means three times the wind load and maybe three times the weight. It needs a (minimum) 75mm diameter mounting tube. Your chimney looks strong but who can tell? Fred [/QUOTE]
