Sadly, we can’t get signals via an antenna due to buildings and trees. Antennas require line of sight. Cable and streaming are our only options, but streaming is very limited when it comes to local news. We’re seriously considering cutting the cable and watching PBS News Hour for national and international news, but local news is, at this time, the problem. I remember when cable TV first started and we were told we’d have options and it would be affordable. For us, neither has come to be. Now with HDTV we are unable to receive signals through the airwaves.
As far as what you need to connect your projector to the computer, I’m not sure, it’s hard to know exactly without knowing your exact setup. If your computer has a tuner built in you could plug in an antenna like this one to get your over the air signal, and then use some sort of wireless video streaming device to get the video source to your projector.
In 2015 The Daily Beast reported that RT hugely exaggerated its global viewership and that its most-watched segments were on apolitical subjects. Between 2013 and 2015, more than 80% of RT's viewership was for videos of accidents, crime, disasters, and natural phenomena, such as the 2013 Chelyabinsk meteor event, with less than 1% of viewership for political videos. In late 2015, all of the 20 most watched videos on its main channel, totaling 300 million views were described as "disaster/novelty". Of the top 100, only small number could be categorized as political with only one covering Ukraine. The most popular video of Russian president Putin shows him singing "Blueberry Hill" at a 2010 St. Petersburg charity event. In 2017, The Washington Post analysed RT's popularity and concluded that "it’s not very good at its job" as "Moscow’s propaganda arm" due to its relative unpopularity. RT has disputed both The Daily Beast 's and The Washington Post 's assessments and has said that their analyses used outdated viewership data.
