While heading east through Waterbury this evening along I-84, I naturally looked to the right and see the tower for (for now) analog channel 20. I now have a question as it relates to WTXX-TV: What is the short dark tower that stands next to the TV tower? I also noticed a three transmitter setup "in front" of that, close to the highway and below the level of WTXX/short dark tower? Who uses these other set ups? ???
