   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.

3. 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.

4. Single-cable distribution - Wikipedia

   en.wikipedia.org/wiki/Single-cable_distribution

   Special LNBs have been developed for use in single-cable distribution systems. All four sub-bands of the Ku band (low frequency/horizontal polarity, high frequency/horizontal polarity, low frequency/vertical polarity, high frequency/vertical polarity) are received by a conventional front end, amplified and downconverted to the L-band, to be fed to a number of SatCR (Satellite Channel Router ...

5. Distributed antenna system - Wikipedia

   en.wikipedia.org/wiki/Distributed_antenna_system

   A distributed antenna system can be implemented using passive splitters and feeders, or active-repeater amplifiers can be included to overcome the feeder losses. In systems where equalization is applied, it may be desirable to introduce delays between the antenna elements.

6. Diplexer - Wikipedia

   en.wikipedia.org/wiki/Diplexer

   A single city radio tower might have a police department antenna on 460 MHz and a fire department antenna on 156 MHz. A diplexer at the top combines the two antenna signals to the single coaxial feedline, and a second identical diplexer inside the building separates the feedline signals to the two dispatch radios.

7. Antenna amplifier - Wikipedia

   en.wikipedia.org/wiki/Antenna_amplifier

   Antenna amplifier for broadcasting service (here: TV broadcasting and FM sound broadcasting). In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead ...
