Ball from under mast

ball-under-mast

This small steel ball was at the base of one of the original masts erected in 1924 for the transmission of the longwave BBC radio service from Borough Hill. Placed between the base of the mast and a concrete block on the ground, the ball gave the mast the necessary flexibility to move with the wind. Incredibly, this little ball could support a mast of roughly 80 tonnes and 150 metres!
