When I was attending UNCC in the early 80s I lived in Hampshire Hills (E. Charlotte) and I had a small portable B&W TV with a single rabbit ear and a UHF loop. I didn't have time for much TV in those days as it was either school or work, but I do remember that in that part of town, I didn't have any issue in receiving 3, 9, 18, 36, & 58. On the other hand, I did live 1 semester on one of the top floors of Moore Hall, one of those 4 white residential highrises at UNCC, and reception up there was awful. It was nothing but ghosts. WSOC was particularly bad and unwatchable. Fortunately the TV stayed turned off and in the closet most of the time.
I seem to remember that in those days, Cablevision only had 11 channels that included WDCA & WSPA. If you paid extra, they would take the trap off your line where you could also get HBO, but it signed off at midnight or something like that. Beyond that there wasn't really any need for cable, in the city, I don't think I got cable until the 2nd 1/2 of the 80s after Cablevision and the much better Vision Cable had expanded their systems to include cable only channels beyond HBO
(That little B&W TV served me well for more than a decade. It was probably manufactured somewhere in the USA in the early 70s and still had a few vacuum tubes in it and nothing but a connection for a twin lead in the back & real mechanical tuners. Built like a tank as it survived dorm living, at least a dozen different moves, getting stored for months, etc. I don't remember what happened to it, but I wish I still had it now. though admittedly, it would be completely useless for OTA TV.)
