8-Port TV Distribution Amplifier. For households with multiple TVs, the Antennas Direct 8-Port TV Distribution Amplifier can split a signal with no noticeable impact on signal quality.
PrimeStar was an American direct broadcast satellite broadcasting company formed in November 1990 by seven cable television companies including Comcast Corp. and TCI Communications Corp. [1] PrimeStar was the first medium-powered DBS system in the United States but slowly declined in popularity with the arrival of DirecTV in 1994 and Dish Network in 1996.

[5] On February 25, 2021, AT&T announced that it would spin-off DirecTV, U-Verse TV, and DirecTV Stream into a separate entity, selling a 30% stake to TPG Inc., while retaining a 70% stake in the new standalone company ...
In November 2017, the FCC approved ATSC 3.0 (Next Gen TV), an updated version of the ATSC standards that supports High Efficiency Video Coding (HEVC), video resolutions of up to 4K ultra high-definition (4K UHD), 120 Hz frame rate, high-dynamic-range (HDR) color, datacasting, and mobile television. Unlike the original digital transition, ATSC 3 ...
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.
Video modulation is a strategy of transmitting video signal in the field of radio modulation and television technology. This strategy enables the video signal to be transmitted more efficiently through long distances. In general, video modulation means that a higher frequency carrier wave is modified according to the original video signal.
A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [1] Typically, RF power amplifiers are used in the final stage of a radio transmitter , their output driving the antenna .
Since the amplifier is at the same location as the speaker, the speaker requires only a line level audio signal as an input. Line level signals are typically around 1-2 volts, and can be transmitted over much smaller cable (typically 20-26 AWG).
