I'm sure it works just as well as a bent coat hanger. Well, almost, anyway.
ANY modern, new fangled fancy looking antenna is junk. ANY claim of much over 65 miles is a sure indicator of bogus marketing.
Antenna technology is pretty mature. I had a StealthTenna at a previous home, and it worked pretty good, for the location I was in. It is about as fancy looking as I'd take a chance on.
Looking at your tvfool, I'd say you can write off getting Fox. Aw shucks, right? If you can live without ABC (& Fox) you MIGHT get by with an indoor antenna, or a modest outdoor one. But considering the different directions, I'd really suggest getting a good UHF/VHF (you'll need both) outdoor antenna on a rotor. And 5 to 10 feet above your 2nd floor roofline would be best.
It's just a one time expense, so don't scrimp too much. You will be living with it for many, many years. You don't want to regret not spending another 30 bucks on a better antenna.
Best of luck to you, and please let us know what you choose to do, and how well it works out for you.
