This reminds me of the promotional campaign that the three Lexington (KY) TV stations of the time (WLEX, WKYT, and WBLG) engaged in, during the 1970s,
cross-promoting all three stations in one cluster with the tagline being "Lexington Television - A Reflection of You". That, too, was an all-UHF market, and they sought to have folks in central and eastern Kentucky watching their stations, rather than those from Louisville, Cincinnati, Huntington, and Knoxville, which in many places might have been easier to receive given the state of UHF signals, antennas, and tuners in those days (those miserable continuous tuners that tended to drift and were sensitive to adjacent- and near-adjacent-channel interference). They did a nice job of expanding their market in all directions and securing cable carriage. It was a case of "a rising tide lifts all boats".
