Obligatory thread-related content: At the beginning of 2011 I was buying a carton a week at about $40/each, so about $160 a month. I now buy 2 120ml bottles of my go-to flavor almost every two months for about $60, but I'll call it $40 a month since I reorder at about 7 weeks and sometimes add a small bottle of a new flavor that looks interesting. I have no idea what the real ones cost today, but going on what I was paying 7 yrs ago about $120/month savings. Well not saved actually, just not spent on tobacco. Who really struggles to figure out how to spend a hundred bucks?
So what does an OTA antenna give you above that? Is a 100 mile range really that if you buy the best? If so, I could get Atlanta, Columbus, and Albany stations direct. I guess that would be the only benefit from an OTA antenna.
In Macon not much. Terrain and antenna elevation matter, as well as what you buy/install. There's a number of phone apps that will help you figure out which direction/strength your local broadcasters are. I use one cleverly named "TV Antenna Helper."
Use that app first and see what's near enough for you to pick up a strong signal. That will guide you on how much antenna to buy, or whether to buy one in the first place. Keep in mind that most broadcast channels actually have several sub channels. If it looks like you're only picking up 3-4 stations, that could actually be 15-20 channels to watch. Just also be aware that, just like the olden days, half of those are PBS, church, and Spanish.
You might get 100 miles if you're on top of the terrain and have an outdoor antenna on a tall mast. Realistically, unless you live deep in a valley you will probably pick up out to 20 miles with a decent indoor antenna, maybe up to 50 miles with an attic or outdoor model. And by that I mean clear signal with no picture defects (weak digital signal does that).
I live about 25 miles NNE of Atlanta. Lots of years ago when DTV first came out, Radio Shack was still in business and I bought a big outdoor antenna and enough pole to put it above the roofline. I am on high terrain and the antenna is about 30' off the ground. It was kind of a production doing that. I also drove in a new ground rod and did all the cabling. Consider all that with your cost. What I get for that is crystal clear reception on most of the Atlanta stations broadcasting east of downtown, which is probably around 70 channels. [oops. just hooked up the big antenna to see, and scanned 140 channels. I usually only use it for backup when cable goes out, which is nearly never. So hadn't scanned in a few years] There's some places that still sell big outdoor antennas, I'd look at the likes of Home Depot or Lowes to start.
The once in a while I park my semi at the Atlanta Petro pointed east so my trailer isn't blocking things, a channel scan has counted up over 100. That's using a better than average indoor antenna that ran me about $60, up on a high shelf.
Hope that gives you an idea what you're missing out on. Or not. Edit to add: PM me with a phone number and a good time, and I'll talk your ear off on the topic.
Edited again: I looked in my phone app. Your success will be determined on how close to I-16 mile marker 9 you are, about 7 miles SE of downtown is where all the broadcast towers are. Good news, all the major networks and probably 20-30 channels of stuff you won't like!
