Transmitfing antennas of 3 sfafions on unique TV łower.

AN unusual new lelevision tower is rapidly nearing complction in Baltimore, Maryland. The transmitting antennas of the three Baltimore stations are supported at identical heights by means of a unique candelabra struc-ture. The top of each antenna soars 730 feet above the ground. or 1049 feet above sea level. This is a con-siderable inerease ovcr the previous individual towers of the TV stations involvcd.

The tower has been several years in planning, designing, and engineering phases, while construction actually be-gan in September. 1958. It is located on a site overlooking Druid Hill Park in northwost Baltimore on ground ad-jacent to the present VVJZ-TV facil-ities. Some of the technical specifica-tions joint ly relcased by WBAL-TV. WMAR-TV. and WJZ-TV. the three participating stations. give an idea of the immensity of the projoct.

Although prcsently reaching 730 feet. the tower was designed for pos-sible futuro extension to 1000 feet. if such a move should ever prove feasible. The threc-sided candelabra supports an antenna at each corner of the tri-angle. Each antenna is over 100-fcet long. The channel-2 radiator is a six-bay turnstile. while channels 11 and 13 utilize travelling-wave designs. Each station currently is broadcasting at maximum allowablc power.

Truss members tie each corncr of the candelabra to a lower support point on the tower. Designed to withstand winds to 165 mph. the tower is con-sidered one of the safest and most ad-vanced designs of its type. The tower is guycd at four points in its height, with cables terminating at three anchors.
