Wow, What an interesting artical. A lot of information on the early days of TV in the US. I was however interested in the Cone Dipole antenna they had display in a couple of the photos. I did a quick search for cone dipole on google but came back with no results. Would be interested in sourcing information on this antenna and maybe it's construction. Will try another indepth search and see what comes to light. If anyone has any information could they pass it to me directly, save causing issues on the group as it is OT.

Klaus Landsberg, a ham (but call sign unknown) was the first chief engineer, and designed the station back in the 1940s. I recently found a writeup of the early days, and page 2 shows the early antenna design. Klaus came up with a very interesting way to get a wide bandwidth: Look at the bottom of page 2 of this file: <http://web.mac.com/zcleve/KlausTribute/KLStories_files/Silva-RoseParade.pdf> Another image of the aural antenna is the second image from the bottom here: <http://www.earlytelevision.org/w6xyz.html> The bottom paragraph of text is incorrect. The hoop antenna is mounted above the platform visible in the bottom image. Other info here: <http://web.mac.com/zcleve/KlausTribute/KlausHome.html> and <http://web.mac.com/zcleve/KlausTribute/KLStories.html> The Stan Chambers writeup is especially interesting. For those that are unaware of it, Stan has been continuously employed by KTLA since 1947 - that's over 60 years at the same station. He's over 80 years old and still goes out on field news assignments.Can anybody in broadcasting top that? He's seen it all - from the early spinning disk experiments to seeing Klaus Landsberg - a ham - invent the studio to transmitter link to the first flying remote (the "Telecopter" in 1958) to today's HD cameras that fit in your hand. ( <http://www.tech-notes.tv/Archive/tech_notes_139.pdf> starting on page 11 ) His 1947 live reports from a electroplating plant explosion become the world's first on-the-spot news coverage. His 1949 on-scene continuous 27½-hour report of the attempt to rescue 3-year-old Kathy Fiscus from an abandoned 14 inch well demonstrated how TV could show live news - until then TV was just evening entertainment. (his grandson, Jaime Chambers, became a reporter at KTLA in 2003, and has two children of his own) Mike
