A coverage map may be produced to indicate the area in which a certain signal strength is delivered. [1] Even if it is 100% accurate (which it never is), a major factor on whether a signal is receivable depends very much on whether the receiving apparatus is sensitive enough to use a signal of that level.
Buildings and trees can hinder your signal strength, but you can use the FCC's digital TV reception map to check for local TV channels and reception quality in your ZIP code. Sources Statistics ...
Signal strength maps provide a metric that quantifies the received power at each location. In turn, propagation maps characterize the propagation channel between arbitrary pairs of locations. Radio maps can be used in a large number of applications, especially in the context of wireless communications .
The "primary service area" is the area served by a station's strongest signal. The "city-grade contour" is 70 dBμ (decibels relative to one microvolt per meter of signal strength) or 3.16mV/m (millivolts per meter) for FM stations in the United States, according to Federal Communications Commission (FCC) regulations.
DirecTV and Dish have launched internet-delivered pay-TV packages, but those have not offset losses on the satellite side. Together, DirecTV and Dish have nearly 20 million customers, which is ...
Within a distance of 35 to 40 miles from the broadcast stations, it is possible that a simple antenna (such as "rabbit ears") is adequate to receive a DTV broadcast signal OTA — at least some of the time for some of the channels. Any television equipped with an ATSC tuner may display DTV broadcasts properly.
The companies reached a new distribution agreement on Monday. A day earlier, Nexstar allowed DirecTV to restore its TV station signals, including KTLA-TV Channel 5, to millions of DirecTV ...
Weak signal strength can also be caused by destructive interference of the signals from local towers in urban areas, or by the construction materials used in some buildings causing significant attenuation of signal strength. Large buildings such as warehouses, hospitals and factories often have no usable signal further than a few metres from ...
