Free TV Channels in San Diego DMA
There are several Free TV Channels in the San Diego DMA including major broadcast networks: ABC, CBS, NBC, FOX and PBS. Local affiliates based in the San Diego DMA receive national feeds from major broadcast networks. Then, they add locally produced news, sports, and other content that is relevant to the local area. The channels are then sent from the local affiliate station to broadcast transmission towers which send the channels over-the-air for free to homes and businesses located within the San Diego DMA. The channels are broadcast using radio frequencies and the typical maximum reception range of the channels is roughly 60-70 miles from the broadcast transmission tower depending on the topography of the area and line of sight. For homes and businesses located closer to the broadcast transmission towers, an indoor antenna should be able to receive channels reliably. For locations further from the broadcast transmission towers or that have line of sight restrictions, an outdoor antenna will likely be the best option for reliable reception.
