I fitted an 80cm dish last year and last night it all but came away from wall. It didn't drop as cables were secured with cable ties. But the bolts came away along with the rawl plugs.
I fixed dish with 10mm rawl plugs and 10x50mm lag bolts.
So I can refit the dish with 10mm rawl plugs along with some grab adhesive, with longer 80mm lag screws.
Or would these be a better choice, ive never used self tapping concrete screws so not sure of their strength...i already have 10mm holes drilled so i presume i need these 12mm bolts...
