Are the Chicago Blackhawks, Bulls and White Sox antenna-worthy? Since my local cable provider has yet to come to an agreement to carry CHSN, the new station that replaced NBC Sports Chicago as the outlet for three of our legacy teams, my only option was to purchase an antenna for the free TV broadcast. The last thing I needed was another device to hook up to my TV, and my local cable provider already charges me about $200 a month to watch sports, movies and “Seinfeld” reruns, so another expense seemed superfluous. But I need my Hawks and Bulls fix after a long season of watching the Cubs and White Sox, so I decided to splurge and go antenna shopping on Wednesday afternoon. From everything I had read, it was a simple installation and would only take about 10 minutes.
