I just "cut the cable" as they say and am using my house's old TV antenna on the roof. I installed a pre-amp and patched the whole thing into the system of coaxials that the cable TV was using under the house. I've had to get back on the roof a few times now (more than I'd to) to try and get all of the channels to come in, but basically, I can either get the ones from the Shinall Mountain towers (THV, KARK) or the PB towers (KATV, AETN, Fox16?) but not both. Is the reception of OTA stations really this flakey in the middle of Little Rock or would I be better served getting a new antenna? Or is it possible that there's a different problem?
