2. 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.

3. Power dividers and directional couplers - Wikipedia

   en.wikipedia.org/wiki/Power_dividers_and...

   From left to right: input, coupled, isolated (terminated with a load), and transmitted port. A 3 dB 2.0–4.2 GHz power divider/combiner. Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio technology.

4. Antenna amplifier - Wikipedia

   en.wikipedia.org/wiki/Antenna_amplifier

   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 cable. An antenna amplifier boosts a radio signal considerably for devices that receive radio ...

5. Digital television adapter - Wikipedia

   en.wikipedia.org/wiki/Digital_television_adapter

   The input digital signal may be over-the-air terrestrial television signals received by a television antenna, or signals from a digital cable system. It normally does not refer to satellite TV , which has always required a set-top box either to operate the big satellite dish , or to be the integrated receiver/decoder (IRD) in the case of direct ...

6. Diplexer - Wikipedia

   That cable would then run from the roof into the house. At a convenient point, a second diplexer would split the two signals apart; one signal would go to the TV set and the other to the IRD of the DBS set-top box. These usually have an antenna input and a diplexer, so that the antenna signal is also distributed along with the satellite.

7. Fiber-optic splitter - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_splitter

   The FBT splitter is one of the most common. FBT splitters are widely accepted and used in passive networks, especially for instances where the split configuration is smaller (1×2, 1×4, 2×2, etc.). [1] The PLC is a more recent technology. PLC splitters offer a better solution for larger applications.
