Abstract :
THE TYPE TY-50/60/70 series vhf television transmitter antennas developed by General Electric (GE) Company consist of stiff steel masts mounting one or more groups of “batwing” style radiating elements. These batwings are connected with 7/8- inch Styroflex feedlines to specially designed junction boxes. Either two or four 3V8-inch transmission lines (depending upon the choice of operational modes) are mounted on the mast with their bases terminating in 3V8-inch flanges between the bottom of the lowest bay and the mast base. The upper ends of these transmission lines are connected directly, or by means of quick disconnect “Tee” feeds, to the proper junction boxes.
