Bexar County
400 Mbps Air Fiber. No contracts. No data caps. Local support you can actually reach.
Macdona is in western Bexar County, just outside San Antonio's Loop 1604 — larger lots, rural homesteads, and properties just past the reach of city-grade internet.
Close to the city doesn't always mean covered: fiber in 78054 is spotty, wired options thin out quickly past the loop, and many households have turned to Starlink. STI's Air Fiber is 400 Mbps down / 25 Mbps up for $65/month — no contract, taxes included.
ZIP code served: 78054
Coverage note: Coverage is solid for most of Macdona. Addresses on the far western edge of 78054 toward the Medina County line, or on rural routes, should call (830) 429-4149 to verify line-of-sight.
Our towers cover both Medina and western Bexar counties, so Macdona installs are handled by the same local team as the rest of our area.
The town was named for George Macdona, the Englishman who owned the townsite when it was platted in 1886.
When something goes wrong, you call (830) 429-4149 — and you talk to someone who lives and works in South Texas. Not a ticket system. Not an overseas call center. And new customers are installed within one business day.

Air Fiber comes from a ground-based tower here in South Texas, not a satellite in orbit. Many Bexar County households compare it with Starlink, whose 400 Mbps plan is $130/month; STI is $65/month with 25 Mbps upload for video calls and remote work — $780/year less than Starlink's 400 Mbps plan.
