Antennae advise - to get the most channels, etc.
Here's a decent one that you can put in an attic or outside. I did a lot of research and this is one of the better options. Personally I'd recommend attic mounting to protect it but I'm always a bit extra cautious. I have it mounted in my Attic and get I think 42 channels at this point.

Here's an amplifier that I used to help boost my signal. Helped me fix some static I had on a couple channels and gave me a couple more.

I use an HD Homerun quatro to broadcast the antennae signal wirelessly to every room in the house. I have firesticks so just installed the app on them and I get a guide with listings, etc. Supposedly your supposed to need to pay for the guide, but I never had to.

Now, with that said, I'd probably prefer to use the firetv recast because the dvr and integration with the firesticks is pretty nice. That's extra money I haven't spent yet since the Quatro works fine but I think it would have nicer DVR features, etc. I heard that it only records in like 720p though so waiting for a new version to come out before I consider moving to it instead.

I got the Quatro when it was on a deal, so $100. Firesticks you can find for $35 normally, $25 occasionally. Antennae and amplifier ran around $85-$90 combined when I got them. I have a bunch of extra cable and connections from when I finished the basement of my house so I didn't have any cost there.
I already had the firesticks in most places so really I spent close to $200 to get the antennae, etc. all up and running and broadcasting to the whole house. You can hook the antennae directly into your cable to spread it through the house but it can weaken the signal so that's up to you on how you want to mess with it. I prefer having the app with guide on all the tvs so it's a pretty decent setup that is totally free once you set it up.
