Looking for a CAI approved aerial installer. I am interested in having a new aerial fitted with new tv points in 3 upstairs bedrooms and 2 downstairs rooms. (If 5 points is an issue for a splitter, 4 points will be acceptable.) Having done some research on the web I am looking for a CAI benchmarked Freeview chimney/wall mounted aerial, ( with heavy duty bracket, not knock in type,) suitable for my area, alloy mast, industry standard cable with appropriate external/internal covers and all holes sealed with silicon sealant.
