That's like in Porter & LaPorte Counties of Indiana, that they're between the Chicago & South Bend markets. Cable systems carry the South Bend stations in LaPorte County because they're usually allowed to carry channels that can be picked up OTA, but also because of significantly viewed status. In Porter County Indiana, cable can only carry WNDU (NBC) & WSBT (CBS) because of significantly viewed status. However, if you have an outdoor antenna you can get both Chicago & South Bend. People in those 2 counties usually have a VHF/UHF combo antenna pointed at Chicago, & a UHF only antenna pointed at South Bend. Since Weigel Broadcasting accepted RF 27 for WCWW-LD South Bend, they made that station 15kw non-directional, while weakening the signal of WCIU Chicago, & people are likely getting interference on RF 27, due to both WCIU & WCWW-LD being on that channel.
As for satellite, those 2 counties of Indiana can only get Chicago stations, but LaPorte County residents consider themselves closer to South Bend, but Neilsen has LaPorte County lumped into the Chicago market, & Indianapolis also has them lumped into the Chicago market. LaPorte County also tried to get on Eastern time, but was denied, because Indianapolis considers them part of Chicago, & Not South Bendm though South Bend is much closer to LaPorte County (like Michigan City & LaPorte).
When it comes to PBS, you're typically only allowed to get your own market PBS stations on cable & satellite. If in between markets, cable will most likely offer a neighboring PBS station, like WNIT South Bend being offered to LaPorte County Indiana residents, along with Chicago area PBS stations WTTW & WYCC Chicago, & WYIN Gary, IN. Satellite, they only offer the main channel of the PBS stations in your market. Markets without their own PBS station, cable will pipe in a PBS station from a neighboring market. Rockford, IL is one market that has yet to get their own PBS station, & relies on WHA Madison Wisconsin & WTTW Chicago on cable, while satellite to my knowledge only offers PBS East & West. My sister lives in Lafayette Indiana, & her market only has 1 TV station. Cable TV is allowed to carry the Indianapolis stations, along with WLFI Lafayette (the only TV station, which is also CBS), & have permission to carry WTTW Chicago, & the subchanels in the digital tier (including WTTW Prime, Create, & V-Me). On satellite, she would automatically be eligible for New York & Los Angeles stations on DirecTV (except for WCBS & KCBS, due to being in WLFI's Grade A coverage area), but not sure about Dish Network.
