To look up translators from a single source, go here:
http://www.rabbitears.info/market.php
Scroll down and select (28) - St George and pull up that list which includes St George and surrounding communities.
What you're seeing are translator clusters that service individual communities and their immediate surrounding area. Usually, all you need is to hit one translator site as most of them are re-broadcasts of Salt Lake City stations, very few of them are anything local or original. You'll have to go through the list, one at a time, and look up each entry to see what each translator is carrying.
