All of Baltimore's television stations at the time had fairly short transmission towers in the medium's early years; channel 13's original tower was located next to the station's studios. In 1959, the three stations—WJZ-TV, WBAL-TV (channel 11) and WMAR-TV (channel 2)—formed a joint venture to build the world's first three-pronged candelabra tower. Constructed behind the WJZ-TV studios and opposite the original channel 13 tower, it was the tallest free standing television antenna in the United States at the time of its completion. The new tower significantly improved channel 13's signal coverage in central Maryland, and also added new viewers in Pennsylvania, Delaware, Washington, D.C. and Virginia.
