You’re mistaken about reception in rural areas ,, do a search on “Gray Hoverman” that antenna design is what I built.. I’m in Orlando and I can get Tampa (70 miles!) stations in addition to Orlando and Melbourne (also about 70 miles). With a good antenna you will discover that there are more ,, WAY MORE ,, stations out there than you think.. one local (18.2) for me has a 24 hour all movie lineup “this” TV.
I believe Orlando is relatively flat, that makes all of the difference.
I grew up in the northeast, and played with antennas (roof, attic and indoor), traps (Jerrold), vhf amplifiers, and all sorts of other toys including a home made channel specific Yagi antenna as a youngster. Elevation is crucial, and PA is filled with valleys, populated valleys. Rural in PA can also mean 100 miles from a low wattage station in Dubois. The state only has two big league cities (both at the extremities), while Florida has at least four.
I never built one, but an outdoor VERY LARGE rhombus antenna is another good (and cheap) way to go. Seventy miles for lower VHF signals (2-5) is not that impressive, and digital TV is more fussy than analog for reception. WIth analog, you might get a snowy picture, with digital such conditions may yield nothing.
If the poster is in northeast PA and is within shooting distance of NYC stations, I would still recommend a good roof antenna for best results. On the other hand, if you are not fussy about WHERE you put your indoor antenna, you might get lucky and find a “hot spot.”
