Just curious, doesn't Tyler have a DMA? Seems like you're a lot closer to Tyler than DFW. SatGuys doesn't have the DMA's listed anymore or I'd look for myself.
Yes, Tyler has a DMA and I am geographically much closer, but I am still in the DFW DMA. DISH knows this and serves me DFW locals (when they aren't in dispute). Atop my 50' tower, I actually have 2 antennae with one pointing East and one pointing North. When the antennae weren't being torn apart by trees, I was receiving OTA locals from both DMAs. If given the choice, I prefer DFW locals as they're just a little more professional commercials. I actually know some of the local news reporters for the Tyler locals, and that's just kind of weird seeing them on TV.
