KTIB has a pretty good signal, covering all of the populated areas of SE LA and even the eastern half of Acadiana. KTIB appears to also have a translator on 103.7 covering Thibodaux/Houma/Raceland
I'm no translator expert, but I believe there's a rule around the translator's coverage and a relation to the primary station's coverage area? If I'm thinking of it correctly, KTIB would be able to feed translators all around New Orleans, Baton Rouge, and "down the bayou".
