For Immediate Release IN THE SPACE of three minutes, a Sikorsky helicopter lines up and lowers a bulky directional antenna (16 feet high, 10 feet wide) atop the 240-foot-radio tower of the L. M. Ericsson Company in Stockholm, Sweden, putting into operation Sweden's first permanent TV link. The country's only other TV transmitter is located on a water tower in Sodertalje, 15 miles away. Since it was physically impossible to assemble the complex parts on the tower, the helicopter was used to lift the 1,300 lb. antenna into place on the 20-story Ericsson tower. The antenna was made to extremely exact tolerances which were held to within 1/20 millimeter per 10 feet of the assembled unit. The TV link has just gone into experimental service. March 19, 1957.
