Lifetime resident, here.
I can't answer about digital antennae, because I have satellite tv. But let's talk about snow:
We will get one to two large snowfalls a year. The snow has been coming later and later in the season the past few years. You'll get more snow in February through March than you will in December. We will get a few inches a couple times in November through January. If you aren't used to snow at all, yes, it will take getting used to. Some of the communities aren't very proficient at clearing the streets. An AWD vehicle is a good idea, especially if you aren't used to driving in the snow.
The Lehigh Valley is a metro area of about 850,000 people, including the cities of Allentown, Bethlehem, and Easton, as well as a bunch of smaller communities. It is the third largest metro area in Pennsylvania, and Allentown is PA's third largest city. Hanover Township has a population of about 11,000 and is served by the Bethlehem Area School District.
Beautiful rolling hills, farmland, suburban neighborhoods, historic downtowns, and even some urban areas. It's a bit of everything.
Halloween is ... weird. Each community schedules Trick-or-Treat. It's not always on the 31st. Most of the time it's on the closest Friday or Sunday to Halloween, and is scheduled for a set number of hours. No, seriously, we do this. I know it's strange.
We take Christmas very seriously. Bethlehem was founded as a Moravian missionary community, and was officially named Bethlehem on Christmas Eve 1741. So Christmas is a big part of the area. Communities decorate their main streets, and the Central Moravian Church Christmas Eve vespers service actually requires tickets.
There is
plenty to do in the area: minor league
baseball,
soccer,
arena football, and
hockey,
community theatre in Allentown,
a great theatre that brings in some pretty good acts in Easton,
a summer Shakespeare theatre series at one of the local colleges. the
hockey arena in Allentown which draws in larger shows, very good restaurants in all three of main cities, fabulous public parks and
trail systems,
art,
science and
history museums, festivals just about every weekend in the summer and fall,

two escape rooms, more craft breweries than you can shake a stick at,
a zoo, ten dog parks (including one in Hanover Township),
an art house theatre that serves food and hosts
a film festival. We even have our own high school theatre
awards show. You can find live music mos weekends, and has active Celtic, Jazz, and Blues music scenes. Plenty of local shopping so you don't even need to go to King of Prussia, but you can, if you want to. Or the outlets near Reading or Hazelton. The area is about 60 miles north of Philadelphia and 90 miles west of New York City.

The Lehigh Valley is served by the Philadelphia affiliates of ABC, NBC, CBS, Fox, and The CW. It has its own PBS station (WLVT 39), NPR station (88.1 FM), and a privately owned local independent tv channel (WFMZ 69).
Property taxes are high in Pennsylvania because it is used to pay for school districts, as opposed to other states. The gas tax just went up a few years ago in Pennsylvania to pay for a plethora of infrastructure needs. Buying alcohol is a little weird because it's not available in all grocery stores due to the state's Liquor Control Board.
Allentown can be dangerous, just like any urban area. Just be careful. We aren't talking New York, Philly, or Detroit levels here, though.
