Besides your local channels, there are several 'digiNet' ancillary (dot) channels available in pretty much every market OTA. As Marc showed his example: Movies!, Decades, and Hero's and Icons feature classic movies. Antenna, MeTV, Grit, Bounce, and Cozi feature classic TV series and sitcoms. Some markets have interesting news and feature networks like: NHK English, BBC, CCTV, and AlJazerra English. Buzzer features 24/7 classic game shows, and NBC-LX features lifestyle programming for Millennial's.
As I showed you, there is a ton of information and resources for setting up an outdoor antenna. Assuming you hired a handyman with a ladder, all it would require of you is to research the best installation for your location, purchase the parts and pieces on-line, then hire someone get up on the ladder to follow the instructions. If you don't want to put forth the effort and a little bit of money, then don't expect good results.
