I haven't had cable or satellite TV service for well over a decade. Just internet and streaming services. I did buy one of those flat OTA antennas a few years ago in case I wanted to watch anything local but I almost never do.
I think that is good advice for anyone who has cut the cable!
For $18, it is a no-brainer:

Features to look for (which the one I linked above has) are:
1) light and dark sides so you can flip it over to fit your decor.
2) A terminal for the cable at the antenna end, so you can switch to dark/light/longer, or just replace a damaged cable.
Obviously, if you live in a metropolitan area you will get 30-60 channels, and if you live rural, you may only get a handful (and since it is Amazon Prime, free return if you get none).
I probably get 35 channels where I live, and by the time I rule out channels which are shopping, evangelist, in Spanish, etc., I have about 5 channels that I can foresee watching...but even for just one decent channel, $18 one time fee, that is a deal!
Quite honestly, I hardly ever use it. The convenience of Hulu and Netflix showing what I want when I want it makes it hard to get down for committing to sit in front of the TV at a certain time (if I was more of a fan of TV, I guess I could use it with a DVR).
However, it sure is handy when I do use it, which is:
1) If a major and/or local story breaks in the news and I want a live feed in real time.
2) My daughter wants to have friends over to watch "The Batchelorette" - God forbid waiting another day to watch it on Hulu. But with social media and for her, I guess that would be like waiting a day to watch the Super Bowl while all of your friends are talking about what happened last night! I happen to get NBC and CBS, but I have to put the antenna on a different wall (90 degrees) for each.
3) If for some reason you lose internet service, it does give you the option to watch tv. That might be very nice to be able to get info if a major earthquake hit, etc.
I used painters blue tape to hang mine (flat on wall or window) to find out where I got best reception and ended up just using that as my final mounting solution. If you get one, you might want one that is white on one side and dark on the other. Aesthetically, my best location for it is on the top of the window where the shade/curtains hide it from the inside (of course it will look kind of "ghetto" from the outside, but mine happens to face the woods). However, I get different channels if I mount on the wall behind the TV. I use it rarely enough that I now keep it tucked behind my A/V cabinet and just hang it when I need to use it - thus the painters tape. For a more "permanent" mount, you can just use push-pins or thumb tacks with colored heads in the two small holes at the top.
