I’ve drilled one of the wall brackets, the holes maybe not perfectly lined up but neither are the originals. At least the U bolt fits so quite pleased overall. thanks to Reg for tips on keeping the drill cool.
Nice work Derek what do you have planned for these brackets
They were originally made to hold a 3" pole for a 1.2 m satellite dish and I want to use them for a 4m antenna, the other bracket has the 3rd support leg so anything attached to them isn’t going anywhere.
