I've NEVER given an Amazon item a 5 star rating but holy cow this thing feels like cheap junk but operates much much higher than any expectations I had. It comes with sticky 3m tape to apply directly to a window. I'm sure it works better in a window but I didn't try it anywhere else comes with a leangthly cord to allow this. First power up and channel search came back with 47 channels !!!!!! No glitching or any problems of that nature I cut the cord with dish and subscribed to PS VUE but it doesn't have local channels so this is perfect to watch nascar on fox this is a perfect antana. I live 15 miles south of tulsa and still received 47 channels did I mention I got 47 freakin channels that's 47 forty SEVEN !!!! buy this !
