Chicago Tower Tech Helmetcams Antenna Removal on Hancock Tower
Looks like a nice day
CHICAGO—A tower tech working on Chicago’s John Hancock Center captured the view from what appears to be a helmetcam, and posted the result on YouTube. L1irnwkr has had nearly 300,000 views of the video showing two tower techs at work to remove the top sections of the west antenna on the Hancock Center, some 1,455 feet in the air, according to The Chicago Architecture Blog.

Some Chicago TV and radio stations are moving from Hancock to other locations around the city, the blog said. Neither the tower techs nor the transmitting TV station were identified.

That was my old channel 32 analog RCA antenna... Installed in 1969, it was a beautiful antenna with one of the best patterns and coverage of the Chicago area until a few weeks after the transition (ch 32 remained on the air as the "lifeboat" station for several weeks). It was fed by 2 6 1/8" coax to an upper and lower antenna section. Originally fed by one 25KW Marconi transmitter until the 2nd rig could be moved from Chicago's Marina City where it had put the station on the air in the early 1960's. The transmitters were upgraded by Townsend to 50KW each in the early 1980's and replaced with a 3 tube Harris MSDC klystron transmitter in 1990. Electrical beam tilt was determined by the line phasing accomplished by a short drip loop in the line. The line was built with RCA "Marmon" clamp 75Ohm transmission line that was finally replaced in the early 2000's. That antenna lasted almost 40 years through Chicago's blistering summers and freezing winters. Another example of amazing 1960's engineering that is all but gone in today's replaceable world...
