A question from a non radio/tv pro. How can an area be considered a DMA when one cannot receive any OTA broadcast stations? For example in eastern Riverside county you obviously cannot pick up any Phoenix TV stations. Same thing as the county that is divided by the Phoenix and Alb TV markets.
And it's probably that way in a lot of other areas like West Texas where presumably the only TV watching is by the wildlife/ maybe a sheepherder with a 200 ft tower and super hi gain antenna.
I'm not a TV person either, but this is my understanding. If W9WI or other TV people are reading this, please feel free to comment and/or correct.
The DMAs are actually a marketing device - DMA stands for Designated Market Area. So even though a region belongs to a DMA, it doesn't necessarily translate to over-the-air reception, although it may determine which local channels are carried by cable and/or satellite TV.
Blythe, California, the only town of any size in eastern Riverside County, gets its OTA television from five translator TV stations rebroadcasting Phoenix stations KTVK, KPHO, KAET, KSAZ and KNXV. The translators are located about 10 mi. east of Blythe, just outside Quartzsite, Arizona, and likely receive their signal via microwave. All are owned by Palo Verde TV Club of Blythe. The Yuma/El Centro stations can also be received in Blythe, but the clearest signal is from the translators.
Apache County, Arizona, is split between the Navajo Nation in the north, and non-tribal land in the south. The north is the only area that receives over-the-air TV anymore; all of the translators in the southern part of the county have now shut down. Most of the Albuquerque stations received in northern Apache County actually come from translators of full-power satellite stations located in Farmington, New Mexico, and Durango, Colorado. Even though southern Apache County is in the Phoenix DMA, when its translator stations were active, they actually relayed Tucson stations, which, located at 9000' atop Mt. Bigelow, came in better, and were, in some cases, actually physically closer than Phoenix.
Utah uses a relay of translators, whereby one translator receives its signal from a Salt Lake City station, and that station is, in turn, received by another station, and so on, until SLC stations are broadcast in St. George UT, over 300 miles away. This was especially true when translators received over-the-air signals and simply relayed them; they might now be using microwave.
Translator TV is mostly used throughout the West; not so commonly in the East, although you'll find a network of translator stations in NE PA, which is how the Scranton/Wilkes-Barre market covers the entire northeastern part of the state, even though it is mountainous.
