XHNAT-TDT is a Grupo Multimedios owned and operated station in Nuevo Laredo, Tamaulipas. The station is primarily affiliated to Multimedios Plus. It serves the Laredo, Texas — Nuevo Laredo areas. When XHNAT first went on the air it was a Galavisión-rebroadcaster Televisa affiliate, part of the Grupo Multimedios concession of 1994, before they decided to switch to their own television network Multimedios Televisión.
