In 1969 a 60-metre tall guyed ground-fed antenna mast was built, which, with its stronger skywave, allowed better signals to the British Isles at night as the prevailing directional antenna. This antenna however was expanded in the 1970s to a system consisting of fove 105-metre tall guyed masts. Nevertheless, it did not work as desired and later it was rebuilt again to the former three-mast antenna. The 60-metre mast used for night transmissions was given a reflector in form of a free-standing 65-metre tall lattice tower with triangular cross section in 1976 for beaming the transmitted power to the British Isles at night.
