Have you checked out locast.org? Free, no need to re-scan for local channels, full HD, no need to worry about azimuths
I donate $5 per month for it, but locast.org has a free option. Can not comment on the free option, because I use my crypto earnings to cover the $5 and fully support reasonably priced offerings.
I am tempted to jump on the AT&T Now bandwagon, especially if HBO continues producing watchable TV.
I had Sling last year - they decided to raise my prices to $100 / month, when I was paying $40. Said no thanks...
