Welcome to the club. This is the antenna and mount I have installed in my attic.
From this I get amazing reception on CBS, ABC, NBC, FOX, CW, PBS and a bunch of secondary stations.
Even with this we still have Hulu to record our shows, sans CBS, which I torrent. Netflix as well. I use AppleTV and connect that to my movies library which is over 600.
I have TWC at the 50 down rate but actually get over 100 down...as they prep to lose customers to Gigafiber from ATT and Google Fiber.
