2. Distributed antenna system - Wikipedia

   en.wikipedia.org/wiki/Distributed_antenna_system

   A single antenna radiating at high power (a) is replaced by a group of low-power antennas to cover the same area (b). The idea was described in a paper by Saleh et al. [2] in 1987. These antennas have recently been employed by several service providers in many areas around the United States.

   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.

4. SMATV - Wikipedia

   en.wikipedia.org/wiki/SMATV

   The system consists of a master antenna and a matching transformer to match the balanced antenna with unbalanced cable and amplifiers. [5] Most antennas have an impedance of around 300 Ω. To convert it to 75 Ω, a matching transformer (or balun) is used. For trunk line isolation, a resistive inductive device known as a splitter is used.

5. Diplexer - Wikipedia

   en.wikipedia.org/wiki/Diplexer

   The dish antenna occupies the high frequencies (typically 950 to 1450 MHz), and the TV antenna uses lower television channel frequencies (typically 50 to 870 MHz). In addition, the satellite also gets a DC to low frequency band to power the dish's block converter and select the dish antenna polarization (e.g., voltage signaling or DiSEqC ).

   In figure 21, an example is shown of a signal split up to feed multiple low power amplifiers, then recombined to feed a single antenna with high power. [52] Figure 21. Splitter and combiner networks used with amplifiers to produce a high power 40 dB (voltage gain 100) solid state amplifier Figure 22. Phase arrangement on a hybrid power combiner.

7. Coupon-eligible converter box - Wikipedia

   en.wikipedia.org/wiki/Coupon-eligible_converter_box

   While an outdoor antenna is required for adequate digital reception in most locations beyond 10–25 miles (16–40 km) from TV transmitters, and smart antenna interfaces were an optionally permitted feature of coupon-eligible converter boxes, [20] there were no subsidies for antennas. Although manufacturers could sell a converter/smart-antenna ...
