Best Indoor Antenna for 50-60 miles away

@MarkKindle - So I was thinking, since I have been doing all of this just to try and get Channel 11 on Hi-VHF, if I just put the reflector behind the store bought Winegard Flatwave Air antenna, it should increase the signal I am currrently getting right? I don’t have a signal tester but when I was doing channel scans I could sometimes get 3 Orange circles on the Tablo scan.

I am heading down to my nieces Sunday AM to try this all out and see if I can finally get her a signal on channel 11. I will share results tomorrow after I am done.
