Once captured, the signal travels down the coaxial cable to the television or an external tuner, where the data is demodulated and decoded into standard video formats like 720p or 1080i. These external models offer significantly higher gain and are the preferred choice for rural viewers or those located more than 30 miles from broadcast towers, as they overcome obstacles like hills and dense foliage.

Conversely, outdoor versions are built to withstand weather elements and are typically mounted on rooftops or poles. Furthermore, ensuring the coaxial connections are tight and using high-quality shielding cables can prevent signal degradation that leads to pixelation.
Because digital signals are more efficient, broadcasters can transmit higher quality video that is free of the ghosting and static common in analog reception. Most modern antenna DTV models are designed to receive both bands to ensure comprehensive coverage of local affiliates.
