I tried to find some 1950s antenna farm pictures but did not succeed. But in the process, I learned four pieces of historical Duluth antenna information that met my own arbitrary interest threshold for sharing in a comment.

1. The Wikipedia page “List of catastrophic collapses of broadcast masts and towers” contains an entry for the collapse of Duluth’s WDIO-TV tower on March 23, 1991. A video showing the aftermath is on YouTube.

2. WDIO: The W for being East of the Mississippi; the D for Duluth; and the IO for 10 (ten), the channel number. I feel like I could have figured that out myself, but did not.

3. At the end of the 1960s, there was a radio tower rather inconveniently located in the middle of the south pier of the lift bridge.
