Fitting ariel socket in wall?

These walls are called paramount partitioning.What you have to do is make a small hole in the ceiling adjacent to the wall,and vertically in line with your aerial point with a nail or something similar,measure back 30-40 mm and drill a 22-25mm hole in the top wooden rail of the partition,then get a length of 20mm pvc conduit(screwfix has it),and ram it down the hole and continue working it back and forwards until you get down far enough to reach your point.I have been doing jobs like this for 20+years and is easy for me,but if you have the necessary tools its not too difficult.
